CS5364-DQZR

ADCs/DACs - Special Purpose Overview

The CS5364-DQZR is a 4-channel audio analog-to-digital converter (ADC) from Cirrus Logic, housed in a 48-pin LQFP package. It utilizes an advanced multi-bit delta-sigma architecture to perform sampling, anti-alias filtering, and conversion, generating 24-bit serial data at sample rates up to 216 kHz per channel. Key electrical specifications include a dynamic range of 114 dB and a THD+N of -105 dB. The device supports selectable audio interface formats including Left-Justified, I²S, and TDM. It features separate logic supplies for control and serial ports ranging from 1.8 V to 5 V, with total power consumption less than 365 mW.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix DQZR against the manufacturer's current ordering information to confirm package type and temperature grade. Confirm RoHS compliance status as datasheet revisions may update environmental declarations. Check for end-of-life notifications or obsolescence notices prior to finalizing procurement plans.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring four differential analog inputs with high-fidelity conversion. Ensure the system design accommodates the required voltage levels for VA, VD, VLS, and VLC supplies. Verify that the host processor supports the desired serial interface format (I²S, LJ, or TDM) and control port protocol (I²C or SPI).

ADCs/DACs - Special Purpose Part Context

The CS5364 belongs to Cirrus Logic’s professional audio ADC family, designed for high-end digital audio systems. It serves as a complete solution by integrating the modulator, digital filter, and decimation stages, thereby eliminating the need for external anti-aliasing filters. The device is footprint compatible with the 8-channel CS5368, facilitating scalable design architectures.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5364-DQZ is the non-reel variant of this component. For higher channel counts, the CS5368 offers footprint compatibility. Other Cirrus Logic audio ADCs such as the CS5361 or CS5363 provide stereo alternatives but differ in channel count and specific performance metrics.
