CS5361K-DZZ

ADCs/DACs - Special Purpose Overview

The CS5361K-DZZ is a 24-bit, multi-bit audio analog-to-digital converter manufactured by Cirrus Logic. It features a 5th-order delta-sigma modulator and digital filtering to perform sampling, conversion, and anti-aliasing without external filters. The device supports system sampling rates up to 192 kHz per channel with a typical dynamic range of 114 dB and -105 dB THD+N. It utilizes a differential analog architecture for noise rejection and includes overflow detection. The component operates within an ambient temperature range of -40°C to +85°C and is housed in a 24-pin TSSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DZZ' indicates the extended industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm pin compatibility with the CS5381 if substituting within the same family. Ensure power supply decoupling follows the recommended layout to maintain specified performance metrics.

ADCs/DACs - Special Purpose Selection Notes

Select this model when an operating temperature range extending to -40°C is required. The device supports both Master and Slave modes for serial audio interface synchronization. Verify that the application requires the specific 24-pin TSSOP footprint and differential input configuration provided by this part number.

ADCs/DACs - Special Purpose Part Context

The CS5361K-DZZ belongs to the CS5361 series of audio ADCs from Cirrus Logic. It shares architectural similarities with other members like the CS5361-KZZ but differs in its specified operating temperature range. The 'DZZ' suffix specifically denotes the automotive-grade temperature rating and TSSOP packaging.

ADCs/DACs - Special Purpose Replacement Considerations

The datasheet states the CS5361 is pin-compatible with the CS5381. Substitution should be verified against the specific temperature and electrical requirements of the target application.

ADCs/DACs - Special Purpose FAQ

What is the difference between the CS5361K-DZZ and CS5361K-KZZ?

The primary difference is the operating temperature range. The CS5361K-DZZ supports -40°C to +85°C, while the CS5361K-KZZ supports -10°C to +70°C.

Does the CS5361 require an external anti-alias filter?

No, the CS5361 uses a 5th-order multi-bit delta-sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter.

How does the overflow detection work on the CS5361?

The CS5361 provides time-multiplexed overflow detection for both left and right channels via the open-drain OVFL pin (Pin 15). It goes active low upon detecting an overrange condition.
