6.1 Overview

The TAC5412-Q1 is from a scalable TAC5x1x-Q1 family of devices. As with the extended family of devices, the TAC5412-Q1 consists of a high-performance, low-power, flexible, mono/stereo, 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. The high dynamic range of this device enables far-field audio recording with high fidelity. 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 make this device well suited for scalable system designs.

The TAC5412-Q1 consists of the following blocks:

  • 2-channel, multibit, high-performance delta-sigma (ΔΣ) ADCs
  • Configurable single-ended or differential audio inputs with high voltage signal swing
  • High-voltage, Low-noise programmable microphone bias output
  • Highly flexible, comprehensive input fault diagnostic
  • 2-channel, multibit, high-performance delta-sigma (ΔΣ) DACs
  • Configurable single-ended, differential or pseudo-differential audio outputs
  • Over Current Diagnostics and Protection for MICBIAS and analog outputs
  • Automatic gain controller (AGC)
  • Advanced Thermal foldback and protection
  • Advanced Battery guard and distortion limiter
  • Programmable decimation filters with linear-phase or low-latency filter
  • Programmable channel gain, volume control, and biquad filters for each channel
  • Programmable phase and gain calibration with fine resolution for each channel
  • Programmable high-pass filter (HPF) and digital channel mixer
  • Pulse density modulation (PDM) digital microphone interface(only available in 5x5mm Package) with high-performance decimation filter
  • 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 TAC5412-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.
