Overview

  • 24-bit stereo audio ADC and DAC: >98 dB SNR
  • Sampling rates from 8 kHz to 96 kHz
  • Low power: 17 mW record, 18 mW playback, 48 kHz
  • 6 analog input pins, configurable for single-ended or differential inputs
  • Flexible analog input/output mixers
  • Stereo digital microphone input
  • PLL supporting input clocks from 8 MHz to 27 MHz
  • Analog automatic level control (ALC)
  • See datasheet for additional features

The ADAU1961 is a low power, stereo audio codec that supports stereo 48 kHz record and playback at 35 mW from a 3.3 V analog supply. The stereo audio ADCs and DACs support sample rates from 8 kHz to 96 kHz as well as a digital volume control.

The record path includes an integrated microphone bias circuit and six inputs. The inputs can be mixed and muxed before the ADC, or they can be configured to bypass the ADC. The ADAU1961 includes a stereo digital microphone input.

The ADAU1961 includes five high power output drivers (two differential and three single-ended), supporting stereo head-phones, an earpiece, or other output transducer. AC-coupled or capless configurations are supported. Individual fine level controls are supported on all analog outputs. The output mixer stage allows for flexible routing of audio.

The serial control bus supports the I2C and SPI protocols. The serial audio bus is programmable for I2S, left-/right-justified, and TDM modes. A programmable PLL supports flexible clock generation for all standard integer rates and fractional master clocks from 8 MHz to 27 MHz

Applications

  • Automotive head units
  • Automotive amplifiers

    We’re considering the implementation of EVAL-AD2428WD1BZ for transmitting audio data to an external board via the A2B bus. Could you confirm if the AD2428 can be operated with the ADAU1761 audio codec serving as the master bypassing DSP ADAU1452?
