Codecs datasheet and documents for CS42426-CQZ

CS42426-CQZ

Codecs Overview

The CS42426-CQZ is a high-performance audio codec featuring six 24-bit digital-to-analog converters and two 24-bit analog-to-digital converters. It supports system sampling rates up to 192 kHz with an integrated low-jitter PLL for jitter attenuation. The device provides 114 dB dynamic range for both ADC and DAC channels, achieving -100 dB THD+N. It includes digital volume control with soft ramp, +/-15 dB input gain adjustment, and seven configurable general-purpose outputs. Operating within a commercial temperature range of -10°C to +70°C, it utilizes a 64-pin LQFP package.

Codecs Feature Summary

Integrated low-jitter PLL for enhanced system clock tolerance
Digital output volume control with soft ramp functionality
Supports logic levels between 1.8 V and 5 V
ADC high-pass filter for DC offset calibration

Codecs Applications

A/V receivers
DVD receivers
Digital speaker systems
Automotive audio systems

Codecs Procurement Notes

Verify the specific suffix CQZ indicates the commercial grade variant (-10°C to +70°C). Confirm the datasheet revision matches the required specifications. Ensure the 64-pin LQFP footprint aligns with the PCB layout. Check for RoHS compliance status in the ordering information section.

Codecs Selection Notes

Select this component for applications requiring wide dynamic range and negligible distortion. Compare against the automotive grade CS42426-DQZ if extended temperature ranges are necessary. Evaluate power supply requirements for VA and VD voltages. Consider the available customer demonstration board for initial evaluation.
