Overview
The ADAU1961WBCPZ-RL is a low-power, stereo audio codec manufactured by Analog Devices Inc. It features 24-bit resolution with sampling rates from 8 kHz to 96 kHz. The device includes two ADCs and two DACs, achieving an SNR of 98 dB for both conversion paths. Power consumption is 17 mW during record and 18 mW during playback at 48 kHz. It operates on a 3.3 V analog supply (2.97 V to 3.63 V) and supports I2C/SPI control interfaces. The component is housed in a 32-lead LFCSP package and is qualified under AEC-Q100 standards.
Feature Summary
- Integrated PLL supporting input clocks from 8 MHz to 27 MHz
- Flexible analog input/output mixers with six configurable analog input pins
- Stereo digital microphone input capability
- Analog automatic level control (ALC) and software-controllable clickless mute
Applications
- Automotive head units
- Automotive amplifiers
- Navigation systems
- Rear-seat entertainment systems
Procurement Notes
Verify the specific ordering suffix BCPZ-RL against official documentation to confirm packaging details. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for such environments. Ensure compatibility with 3.3 V logic levels for all digital interfaces before integration into the target system design.
Selection Notes
Select this component when a high-performance stereo codec with integrated headphone drivers is required. It is suitable for applications needing flexible analog routing and digital microphone support. Verify that the 32-lead LFCSP package fits the available PCB space and thermal constraints. Ensure the host processor supports the required serial data formats like I2S or TDM.
Part Context
This part belongs to the ADAU1961 series of audio codecs designed for automotive and consumer electronics. It provides a compact solution for integrating high-fidelity audio recording and playback functions. The device combines analog front-end capabilities with digital signal processing controls in a single chip.
Replacement Considerations
