7.1 Overview

The TAC5212 is from a scalable family of devices. As part of the extended family of devices, the TAC5212 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 ruggedized communication equipment, IP network cameras, Professional Audio, 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 system designs. Package, performance, and compatible configuration registers across extended families make this device well-suited for scalable system designs.

The TAC5212 consists of the following blocks:

  • 2-channel, multibit, high-performance delta-sigma (ΔΣ) ADCs
  • Configurable single-ended or differential audio inputs with 2Vrms signal swing
  • Low-noise programmable microphone bias output
  • 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 with a high-performance decimation filter
  • Dual I2S or TDM Interface with Independent Sample Rate(Synchronous)
  • Synchronous Sample Rate Converter(SRC)
  • 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 TAC5212 for configuring the control registers is supported using an I2C and SPI 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.
