CS5361K-KSZR

ADCs/DACs - Special Purpose Overview

The CS5361K-KSZR is a commercial-grade, 24-bit audio analog-to-digital converter manufactured by Cirrus Logic. It utilizes an advanced multi-bit delta-sigma architecture to achieve a typical dynamic range of 114 dB and -105 dB THD+N. The device supports system sampling rates up to 192 kHz per channel with integrated digital filtering that eliminates the need for external anti-alias filters. Operating on a single 5 V supply, it consumes 135 mW and features differential analog inputs, overflow detection, and a serial interface compatible with I2S and Left Justified formats.

ADCs/DACs - Special Purpose Feature Summary

ADCs/DACs - Special Purpose Applications

• Audio/Video receivers
• DVD-R and CD-R recorders
• Digital mixing consoles
• Effects processors

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix K-SZR corresponds to the 24-pin SOIC package and commercial temperature range (-10°C to +70°C). Ensure compatibility with existing power supply rails and logic levels before integration.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring high-fidelity audio conversion without external anti-alias filtering. Choose the K-SZR variant for standard commercial operating temperatures. Verify that the host system can provide the necessary master clock frequencies (e.g., 12.288 MHz for 48 kHz sampling) if operating in Master Mode.

ADCs/DACs - Special Purpose Part Context

This component belongs to the CS5361 family of audio ADCs. It is pin-compatible with the CS5381. The K-SZR designation specifically identifies the lead-free, 24-pin Small Outline Integrated Circuit (SOIC) package version intended for commercial ambient temperature operation.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5381 is a pin-compatible alternative within the same product family. Verify functional equivalence regarding specific performance metrics and configuration requirements before substitution.

ADCs/DACs - Special Purpose FAQ

Does the CS5361 require an external anti-alias filter?

No, the internal 5th-order multi-bit delta-sigma modulator followed by digital filtering and decimation removes the need for an external anti-alias filter.

How is the overflow condition indicated?

Overflow detection is provided via an open-drain, active-low OVFL output pin (Pin 15) that signals overrange conditions on either the left or right channel.

What is the maximum supported sample rate?

The device supports system sampling rates up to 192 kHz per channel when configured in Quad Speed Mode.
