CS5361-KZZR

ADCs/DACs - Special Purpose Overview

The CS5361-KZZR is a 24-bit, multi-bit audio analog-to-digital converter (ADC) manufactured by Cirrus Logic. It utilizes a 5th-order delta-sigma modulator architecture to achieve a typical dynamic range of 114 dB and -105 dB THD+N at system sampling rates up to 192 kHz per channel. The device integrates digital filtering and decimation, eliminating the need for external anti-alias filters. It features differential analog inputs, supports logic levels between 2.5 V and 5 V, and includes high-pass filter and DC offset calibration capabilities. The component operates within a temperature range of -10°C to +70°C and consumes 135 mW at 5 V supplies.

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for lead-free certification documentation. Ensure the specific KZZR suffix corresponds to the TSSOP-24 package variant required for the design. Validate that the commercial temperature grade (-10°C to +70°C) meets the operational environment specifications.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high dynamic range and low distortion in stereo audio digitization. The integrated digital filter simplifies PCB layout by removing external anti-aliasing components. Ensure the system clocking scheme supports either Master or Slave modes as needed. Verify that the differential input impedance and full-scale input voltage requirements align with the preceding analog buffer stage.

ADCs/DACs - Special Purpose Part Context

The CS5361 belongs to Cirrus Logic's family of multi-bit audio ADCs. It is pin-compatible with the CS5381, which offers higher dynamic performance. The KZZR suffix denotes the commercial temperature grade version packaged in a 24-pin Thin Shrink Small Outline Package (TSSOP). Other variants include the KSZ (SOIC package) and DZZ (automotive temperature grade).

ADCs/DACs - Special Purpose Replacement Considerations

The CS5381-KZZR is a pin-compatible alternative offering improved dynamic range. Verify that the higher performance metrics of the substitute do not introduce compatibility issues with existing power supply constraints or thermal management designs.
