CS5364-CQZR

ADCs/DACs - Special Purpose Overview

The CS5364-CQZR is a 4-channel, 24-bit audio analog-to-digital converter (ADC) from Cirrus Logic. It utilizes an advanced multi-bit delta-sigma architecture to perform sampling, anti-alias filtering, and conversion without external components. The device supports sample rates up to 216 kHz per channel and delivers a typical dynamic range of 114 dB with -105 dB THD+N. It features selectable serial audio interfaces including Left-Justified, I²S, and TDM formats. Power consumption is less than 365 mW under standard operating conditions.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CQZR' against the manufacturer's current ordering information to confirm package type and reel specifications. Ensure the component grade matches the required ambient operating temperature range for the target application.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring four differential analog inputs and high-speed TDM interface support. Verify that the system logic levels for the control and serial ports align with the available 1.8 V to 5 V supply options provided by the dedicated level translators.

ADCs/DACs - Special Purpose Part Context

This component belongs to the Cirrus Logic CS536x series of audio ADCs. It shares footprint compatibility with the 8-channel CS5368 variant, facilitating design scalability. The device integrates an on-chip oscillator driver and operates as either a system clock master or slave.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5364-CQZ is a non-reel version of the same functional device. For higher channel counts, the CS5368 offers footprint compatibility.
