Overview
The ADAU1961WBCPZ is a stereo audio codec featuring 24-bit ADCs and DACs with an SNR of 98 dB. It supports sampling rates from 8 kHz to 96 kHz and operates on a single 3.3 V analog supply, consuming 17 mW during record and 18 mW during playback at 48 kHz. The device includes six configurable analog input pins, flexible mixers, and a stereo digital microphone interface. Output drivers provide two differential stereo lines, two single-ended stereo lines, and one mono headphone driver. Control is managed via I2C or SPI interfaces, while serial audio data supports I2S, left/right-justified, and TDM modes.
Feature Summary
- Integrated PLL supporting input clocks from 8 MHz to 27 MHz for flexible clock generation
- Analog automatic level control (ALC) with software-controllable clickless mute
- Flexible analog input/output mixers allowing configurable routing of audio signals
- Supports AC-coupled or capless configurations for output transducers
Applications
- Automotive head units
- Automotive amplifiers
- Navigation systems
- Rear-seat entertainment systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for such environments. Cross-reference the datasheet revision to validate all electrical specifications prior to integration into the design.
Selection Notes
Select this component when a low-power stereo codec with integrated headphone drivers is required. Ensure the system design accommodates the 3.3 V analog supply voltage and utilizes the available serial control interfaces. Verify that the package dimensions fit the PCB layout constraints and that thermal dissipation requirements are met for the LFCSP-32 package.
