CS4207-DNZR

Codecs Overview

The CS4207-DNZR is a low-power, multi-channel High Definition Audio Codec manufactured by Cirrus Logic. It integrates two stereo analog-to-digital converters (ADCs) and three digital-to-analog converters (DACs), including a dedicated headphone amplifier. The device supports sample rates up to 192 kHz for DACs and S/PDIF interfaces, and up to 96 kHz for ADCs. Key electrical specifications include a dynamic range of 105 dB for the ADCs and 110 dB for the line-out DACs. The codec operates with variable power supplies: 1.5 V to 1.8 V for the digital core, 3.3 V to 5.0 V for the analog core and headphone drivers, and 1.5 V to 3.3 V for the HD bus interface logic.

Codecs Feature Summary

• Integrated ground-centered headphone amplifier that eliminates the need for external DC-blocking capacitors through an internally generated negative supply.
• Built-in digital audio interface receiver and transmitters featuring a high-performance asynchronous sample rate converter for clock alignment.
• Microphone input path equipped with a programmable-gain pre-amplifier and selectable bias voltage settings.
• Supports independent D0 and D3 power states for individual ADCs and DACs to minimize power consumption.

Codecs Applications

• Portable computing systems requiring low power consumption and minimal board space.
• High-definition audio playback and recording applications in consumer electronics.
• Digital audio interfaces utilizing S/PDIF transmission and reception protocols.

Codecs Procurement Notes

Verify the specific suffix 'DNZR' against official documentation to confirm it denotes the Automotive grade variant (-40°C to +105°C) packaged in a Reel format. Ensure compatibility with the required operating temperature range and packaging constraints before finalizing procurement orders.

Codecs Selection Notes

Select this component when a system requires integrated S/PDIF handling alongside standard PCM audio conversion. The inclusion of a ground-centered headphone driver simplifies analog output design by removing passive components. Verify that the available pin count and package dimensions fit the target PCB layout constraints.

Codecs Part Context

This part belongs to the CS4207 family of High Definition Audio Codecs from Cirrus Logic. The family provides multi-channel audio processing capabilities designed for portable and desktop applications. The DNZR suffix typically indicates the automotive temperature rating and reel packaging configuration within the product lineup.

Codecs Replacement Considerations

Check for discontinued status notifications as the CS4207 series has faced end-of-life actions. Consult manufacturer documentation for officially confirmed substitute part numbers or next-generation replacements that maintain pin and functional compatibility.
