Codecs datasheet and documents for CS4245-DQZ

CS4245-DQZ

Codecs Overview

The CS4245-DQZ is a highly integrated stereo audio CODEC manufactured by Cirrus Logic Inc. It performs stereo analog-to-digital and digital-to-analog conversion of up to 24-bit serial values at sample rates up to 192 kHz. The device features a 6:1 stereo input multiplexer, a programmable gain amplifier with ±12 dB gain in 0.5 dB steps, and stereo microphone inputs with +32 dB gain. It supports selectable serial audio interface formats including Left-Justified, I²S, and Right-Justified. The component operates with 1.8 V to 5 V logic levels and includes Popguard technology to minimize output transients.

Codecs Feature Summary

Multi-bit delta sigma modulators for both ADC and DAC paths
Integrated level translators for wide logic voltage interfacing
Selectable auxiliary analog output for signal monitoring
Internal digital loopback capability

Codecs Applications

High-fidelity stereo audio systems
Digital audio programs requiring de-emphasis compatibility
Automotive grade audio implementations

Codecs Procurement Notes

Verify the specific suffix DQZ against official documentation to confirm it denotes the Automotive temperature grade (-40°C to +105°C). Confirm package type is 48-pin LQFP. Check current product status as discontinuation notices may affect availability.

Codecs Selection Notes

Select this component when a stereo CODEC with high dynamic range and low latency anti-alias filtering is required. Ensure the design accommodates the 48-pin LQFP footprint. Verify power supply requirements match the specified 3.3 V to 5 V ranges for both analog and digital sections.

Codecs Part Context

This part belongs to the CS4245 series of stereo audio CODECs from Cirrus Logic. It is pin-compatible with the CS5345. The CDB4245 evaluation board is available for device implementation suggestions. The datasheet revision is DS656F3.
