Headunit

Description

Infotainment systems combine entertainment, multi-media and driver information functions in one module. They offer AM/FM or satellite radio, CD/DVD player for music and video, navigation system, data and multimedia ports (USB, Blue tooth, line in, line out, video in) as well as general and vehicle status information.

The Audio line level input from the source is converted into digital samples by the ADC and feed to the system's Audio Processor.

On the output side, in a typical system, DACs convert the digital output to an analog signal, which is amplified to the levels needed by the speakers used with the system. Depending on the system specifications and Audio Processor used, these DACs may be fully integrated in the processor to minimize cost and size or could be discretely implemented to maximize audio quality and system performance.

However, alternative topologies can be implemented to avoid analog conversion of the output audio digital signal altogether. A digital-input Class-D Audio Amplifier processes the processor's data-stream directly, reducing size and component count even further.

To further reduce component count, the audio input and output signal conditioning can be combined into a single codec that combines both DACs and ADCs. and can also include embedded processing to perform audio digital signal processing.

By using Class-D Audio amplifiers the system’s power efficiency can exceed 90% while maintaining top of the line audio fidelity. This improved efficiency leads to significant size, weight and heat reductions; and, although Class-D Audio amplifiers require external inductors, new lower-cost automotive-grade inductors allow system designers keep system cost down and closer to parity to comparable Class-AB based audio systems at a fraction of the size and weight.

TI’s class-D car audio solutions exhibit extremely low EMI levels and are being used in OEM systems with stringent EMC requirements, such as CISPR25-L5, without additional, and costly, filtering or shielding.

Finally, automotive systems are subject to very harsh operating environments and are expected to perform at enhanced levels of reliability. TI's full-featured automotive class-D audio amplifiers include built-in load diagnostics functions for detecting and diagnosing misconnected outputs to help reduce test time during the manufacturing process and load-dump protection to withstand high voltage transients typically present in automotive systems' power supplies.

External Amplifier

Description

Factory-installed infotainment systems combine entertainment, multi-media and driver information functions in one module. They offer AM/FM or satellite radio, CD/DVD player for music and video, navigation system, data and multimedia ports (USB, Blue tooth, line in, line out, video in) as well as general and vehicle status information.

Until recently, even the best factory-installed systems provided a sub-par listening experience to discerning customers. Upgrading the factory-installed system with vastly-improved aftermarket components was a must when customers demanded top-of-the-line automotive audio quality.

Today, in high-end cars, this is no longer the case as premium OEMs (original equipment manufacturer) systems can match, or even surpass, an equivalent aftermarket system in almost every aspect. These high-end systems include, in addition to the headunit infotainment system, powerful factory-installed external amplifiers that are separate from the headunit to achieve the best sound quality.

For low-end and mid-end vehicles with basic head unit implementations and no external amplifier, adding an external aftermarket amplifier vastly improves sound quality.

In a typical external amplifier, there are three parts to a power amplifier: the preamp section (where the signal comes into the amp and where devices like crossovers and equalizes are located), the power supply (which provides the energy to power the amplifier) and the amplifier itself (which drives the speakers).

The preamp section of the amplifier, very likely, has a gain control stage; this control is used to amplify the signal coming from the headunit to ensure the amplifier is driven to its maximum power level. Depending on the amplifier’s topology, this stage can be implemented with discrete operational amplifiers and discrete components, with a fully integrated ADC with analog front end or with a CODEC solution.

In addition, higher-end amplifiers’ preamp stages perform some level of signal processing to enhance the audio output (like crossover or equalization); this signal processing is done in the digital domain using a processor or DSP. Fully-integrated Audio CODECs with embedded mini-DSP convert the input audio analog signal to digital information, perform the audio signal enhancement and converts it back to analog. Alternative topologies include discrete ADC/DAC combo for additional system flexibility.

For the actual amplifier stage, by using Class-D Audio amplifiers the system’s power efficiency can exceed 90% while maintaining top of the line audio fidelity. This improved efficiency leads to significant size, weight and heat reductions; and, although Class-D Audio amplifiers require external inductors, new lower-cost automotive-grade inductors allow system designers keep system cost down and closer to parity to comparable Class-AB based audio systems at a fraction of the size.

TI’s class-D car audio solutions exhibit extremely low EMI levels and are being used in OEM systems with stringent EMC requirements, such as CISPR25-L5, without additional, and costly, filtering or shielding.

Instrument Cluster

Description

The instrument cluster is the main means to display information and status of vehicle systems and drive conditions. What was once a basic display, now includes gauges for various parameters, indicators and status lights as well as displays and sometimes sophisticated acoustical effects.

Depending on the target customer base, the instrument cluster audio subsystem can be implemented in multiple ways. Higher-end systems prioritize higher sound pressure level (SPL), audio quality and reliability, while cost is a top priority in lower-end systems.

Higher SPL helps overcome interior noise, particularly at high road speeds. SPL is directly related to the output power delivered by the speaker and to the output power delivered by the audio amplifier. At constant speaker impedance, the power delivered to the speaker by the amplifier depends on the amplifier’s efficiency and voltage.

In terms of efficiency, Class-D amplifiers have the upper hand (compared to Class-AB amplifiers). Class-D amplifiers can deliver substantially higher efficiency levels in the 80-90 percent range, whereas Class-AB amplifiers can deliver 30-40 percent and require more complex thermal management.

For increased SPL, a higher-voltage amplifier typically delivers more power and is more likely to withstand the high-voltage transients typical in automotive systems.

Automotive original equipment manufacturers (OEMs) increasingly demand higher audio quality to provide a tailored user experience that enhances brand recognition and affinity.

Audio quality specs depend on the amplifier’s total harmonic distortion (THD) and the signal chain’s signal-to-noise ratio (SNR) and dynamic range (DR).

Automotive applications are known to demand higher levels of reliability compared to personal electronics applications; AEC-Q100-qualified devices offer a high level of reliability tailored for automotive applications.

In addition, Q100-qualified audio amplifiers with integrated diagnostics and protection take reliability to an even higher level. For example, audio amplifiers with integrated diagnostics can signal to an external microprocessor whether the speaker has been disconnected or has its terminals shorted to each other, to ground or to its voltage rail.

Integrated diagnostics are particularly important during car assembly to ensure that the sound system has been properly installed and that no shorts occurred during speaker installation. Also, this feature can help ensure that safety-related systems, like instrument clusters and other telematics that alert users of out-of-the-ordinary conditions, are continuously operational.

Much has been said about how Class-AB audio amplifiers are more cost-effective than their Class-D counterparts. When considering the IC by itself this may be true; but system designers must consider the cost of the whole audio solution.

For example, the fundamental differences in efficiency between Class-AB and Class-D audio amplifiers have an impact on the audio solution cost. The lower-efficiency Class-AB amplifier requires more complex and expensive thermal management; expensive heatsinks and an additional printed circuit board (PCB) area for thermal dissipation are very common downsides to using Class-AB amplifiers.

eCall & Telematics

Description

E-Call is an automated emergency call for serious road accidents,. In a car accident event, the eCall system automatically communicates and broadcasts the vehicle location to the nearest emergency center, dramatically shortening emergency services response time

Most importantly, eCall systems need to run reliably and autonomously for long periods of time using only backup battery power. Class-D amplifiers can deliver substantially higher efficiency levels in the 80-90 percent range, whereas Class-AB amplifiers can deliver 30-40 percent and require more complex thermal management.

Enhanced EMI suppression to improve sound immunity ensures loud and clear audio quality; which is imperative in an eCall system where external conditions can sometimes overwhelm the emergency call.

TI’s Class D amplifier's wide supply voltage range and low minimum input voltage ensures robust telematics and eCall designs that could be powered by a single-cell battery cell and an appropriate power management topology, even in case the car lead-acid battery connection is severed in an accident. Reduced battery cell counts improves the system size, weight and cost.

In addition, TI’s Class D amplifier's over-voltage and load dump protection, power cycling support and speaker open-load detection during initial power-up ensure robust operation in harsh automotive environments and simplify failure analysis.
