6.1 Overview

The TAC5301-Q1 consists of an automotive low-power, flexible, mono, audio analog-to-digital converter (ADC) and audio digital-to-analog converter (DAC) with extensive feature integration. This device is intended for automotive applications such as telematics control unit, hands-free in-vehicle communication, emergency call, and multimedia applications. This device integrates a host of features that reduce cost, board space, and power consumption in space-constrained automotive sub-system designs. Package, performance, and device-compatible configuration registers across extended family make this device well suited for scalable system designs.

The TAC5301-Q1 consists of the following blocks:

  • Mono, multi-bit, low-power delta-sigma (ΔΣ) ADCs
  • Configurable single-ended or differential audio inputs
  • High-voltage, low-noise programmable microphone bias output using external HVDD supply
  • Stereo, multibit, high-performance delta-sigma (ΔΣ) DACs
  • Configurable single-ended, differential or pseudo-differential audio outputs
  • Input/output mix/mux Options
  • Over current protection for MICBIAS
  • Automatic gain controller (AGC) for ADC channels and Dynamic range controller (DRC) for DAC channels
  • Advanced thermal foldback and protection
  • Advanced battery guard and distortion limiter
  • Programmable decimation and interpolation filters with linear-phase, low-latency and ultra low-latency response options
  • Programmable channel gain, volume control, and biquad filters for each ADC and DAC channel
  • Programmable phase and gain calibration with fine resolution for each ADC channel
  • Programmable high-pass filter (HPF) and digital channel mixer for ADC and DAC channels
  • Integrated low-jitter, phase-locked loop (PLL) supporting a wide range of system clocks
  • Integrated digital and analog voltage regulators to support single-supply operation

Communication to the TAC5301-Q1 for configuring the control registers is supported using an I2C interface. The device supports a highly flexible audio serial interface [time-division multiplexing (TDM), I2S, or left-justified (LJ)] to transmit audio data seamlessly in the system across devices.

The TAC5301-Q1 can support multiple devices by sharing the common TDM bus across devices. Moreover, the device includes a daisy-chain feature as well. These features relax the shared TDM bus timing requirements and board design complexities when operating multiple devices for applications requiring high audio data bandwidth.

Table 6-1 lists the reference abbreviations used throughout this document to registers that control the device.
