CS5381K-KSZR

Analog To Digital Converters (ADC) Overview

The CS5381K-KSZR is a stereo audio analog-to-digital converter manufactured by Cirrus Logic. It utilizes a 5th-order multi-bit delta-sigma architecture to perform sampling, anti-alias filtering, and conversion simultaneously. The device provides 24-bit resolution with a dynamic range of 120 dB and -110 dB THD+N. It supports output sample rates up to 216 kHz per channel via a serial audio interface. Electrical specifications include an analog supply voltage of 5 V (4.75 V to 5.25 V) and digital supplies of 3.3 V to 5 V. The component is housed in a 24-pin SOIC package and operates within a commercial temperature range of -10°C to +70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix K-SZ for the 24-pin SOIC package variant against the datasheet ordering information. Confirm that the required logic levels align with the supported 2.5 V to 5 V interface supply range. Ensure power sequencing follows the recommended reset stability guidelines to prevent glitches.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 24-pin SOIC footprint is required instead of the TSSOP option. Verify system clocking requirements for Master or Slave modes, as MCLK ratios differ based on the selected speed mode. Consider the internal reference stability and external capacitor sizing on FILT+ to meet low-frequency distortion specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the CS5381 series of high-performance audio ADCs. It shares architectural similarities with the CS5361 but offers improved dynamic range. The device integrates differential analog inputs and digital filters, eliminating the need for external anti-alias filters in standard audio applications.

Analog To Digital Converters (ADC) Replacement Considerations

The CS5381-KZZR (TSSOP package) is pin-compatible and functionally equivalent regarding electrical performance. Other Cirrus Logic audio ADCs may require significant schematic redesign due to differing pinouts or interface protocols.
