TAS5615 (NRND)

Analog input 160W Stereo (300W total) class D amplifier with integrated feedback

 

Not Recommended for New Designs (NRND)

Replaced By TPA3251 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. The TPA3251 delivers a better performance with a lower THD+N (<0.005% @1W into 4Ω) and a signal bandwidth of up to 100kHz for true Ultra-HD / High Resolution sound while supporting output levels up to 175W Stereo / 350W Mono.
TPA3255 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. For applications with higher power requirements, the TPA3255 delivers the same performance as the TPA3251 for output levels up to 315W Stereo /600W Mono.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

Description

The TAS5615 is a high-performance analog input class-D amplifier with integrated closed-loop feedback technology (known as PurePath™ HD technology). It has the ability to drive up to 160 W(1) stereo into 8- speakers from a single 50-V supply.

PurePath HD technology enables traditional AB-amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class-D amplifiers.

Ultralow 0.03% THD+N is flat across all frequencies, ensuring that the amplifier does not add uneven distortion characteristics, and helps maintain a natural sound.

The efficiency of this class-D amplifier is greater than 90%. Undervoltage protection, overtemperature, clipping, short-circuit and overcurrent protection are all integrated, safeguarding the device and speakers against fault conditions that could damage the system.
