ADAU71067Z-CS

Overview

The ADAU71067Z-CS is a high-performance, low-power audio codec designed for portable and battery-powered applications. It integrates a stereo analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) with Sigma-Delta modulation. The device supports multiple sampling rates up to 96 kHz and offers programmable gain amplifiers (PGAs) on the input channels. It features a serial interface compatible with standard DSP and microcontroller protocols, including I2S and TDM modes.

Feature Summary

• Integrates stereo ADC and DAC with Sigma-Delta modulation for high-fidelity audio conversion
• Includes programmable gain amplifiers (PGAs) to optimize signal-to-noise ratio for various input levels
• Supports flexible serial interfaces including I2S and TDM for easy integration with digital processors
• Designed for low power consumption suitable for battery-operated portable devices

Applications

• Portable media players and smartphones
• Voice recognition modules
• Bluetooth audio transceivers
• Digital voice recorders

Procurement Notes

Verify the specific suffix 'Z-CS' against the manufacturer's current ordering guide to confirm package type and temperature range. Ensure compatibility with system voltage requirements and clocking configurations before procurement. Cross-reference the datasheet revision date to ensure all errata and updates are accounted for in the design phase.

Selection Notes

Select this component when a compact, low-power solution is required for stereo audio processing. Consider the integrated PGAs if external amplification is undesirable. Verify that the host processor supports the required serial interface mode and data format. Evaluate power supply constraints as the device operates from a single supply voltage.

Part Context

This part belongs to Analog Devices' ADAU series of audio codecs, which are optimized for mobile and consumer electronics. The Z-CS suffix typically indicates a specific package variant and commercial temperature range. It complements other ADAU components by providing essential analog front-end capabilities for digital audio systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADAU family, such as the ADAU71068 or ADAU71069, depending on channel count and feature requirements. Verify electrical specifications and software compatibility if substituting with non-ADI parts. Consult official substitution guides for validated replacements.
