CS5381-KSZ

Analog To Digital Converters (ADC) Overview

The CS5381-KSZ is a 24-bit, stereo audio analog-to-digital converter (ADC) utilizing a multi-bit delta-sigma architecture. It features two differential analog inputs and supports output sample rates up to 216 kHz per channel. The device integrates internal digital filtering, decimation, and an anti-alias filter, eliminating the need for external components. Key electrical specifications include a 120 dB dynamic range, -110 dB THD+N, and operation with a 5 V analog supply and 3.3 V to 5 V digital/logic supplies. It is housed in a 24-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity and physical condition upon receipt. Confirm that the part matches the specified 24-SOIC package and pinout. Check for any manufacturing notices or obsolescence status changes prior to integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-fidelity audio conversion with minimal external filtering. Ensure the system clock frequency aligns with the desired output sample rate using the MCLK divider settings. Verify that the logic voltage levels (VL) are compatible with the downstream digital processor interface.

Analog To Digital Converters (ADC) Part Context

The CS5381-KSZ belongs to the Cirrus Logic CS5381 series of audio ADCs. It is pin-compatible with the CS5361, allowing for potential design swaps between these models while maintaining board layout consistency.

Analog To Digital Converters (ADC) Replacement Considerations

The CS5361 is a pin-compatible alternative within the same family. Designers should verify specific performance differences, such as dynamic range and power consumption, when substituting parts.
