Overview
The ADAU1361BCPZ-R7 is a stereo audio codec manufactured by Analog Devices Inc., featuring 24-bit resolution for both analog-to-digital and digital-to-analog conversion. It supports sampling rates from 8 kHz to 96 kHz with an integrated PLL accepting input clocks between 8 MHz and 27 MHz. The device operates on analog and digital supplies ranging from 1.8 V to 3.65 V, consuming as low as 7 mW during record or playback at 48 kHz. It includes six configurable analog inputs, multiple output drivers, and serial control interfaces.
Feature Summary
- Integrated microphone bias circuitry and support for stereo digital microphone inputs alongside configurable analog line-level inputs.
- Flexible analog output architecture providing differential stereo, single-ended stereo, and capless headphone driver capabilities.
- Programmable serial data port supporting I2S, left/right-justified, and time-division multiplexing modes for digital audio transport.
Applications
- Smartphones and multimedia phones
- Digital still cameras and digital video cameras
- Portable media players and portable audio players
Procurement Notes
Verify the specific -R7 suffix indicates reel packaging when sourcing components. Confirm that the ordering information matches the required package type and tape-and-reel specifications provided in the manufacturer's official documentation before finalizing procurement orders.
Selection Notes
Select this component for battery-powered applications requiring high dynamic range and low power consumption. Ensure the system design accommodates the 1.8 V to 3.65 V supply voltage range and utilizes the integrated PLL for flexible clock generation from external main clocks.
Part Context
This part belongs to the ADAU1361 series of low-power stereo audio codecs. It is designed for general-purpose audio processing in portable electronics, offering a compact 32-lead LFCSP package suitable for space-constrained designs while maintaining high-fidelity audio performance.
Replacement Considerations
Consult the official datasheet ordering guide for confirmed substitute part numbers. Verify pin compatibility and electrical specifications against any alternative devices before implementation.
FAQ
What are the supported digital audio interface modes?
The serial data port supports I2S, left-justified, right-justified, and time-division multiplexing (TDM) modes.
How does the device handle microphone inputs?
It includes an integrated microphone bias circuit and supports both analog microphone inputs via configurable PGA pins and stereo digital microphone inputs.
What is the function of the exposed pad on the package?
The exposed pad is connected internally to the grounds and should be soldered to the ground plane to increase solder joint reliability and maximize thermal capability.
