CS5381-KZZ

Analog To Digital Converters (ADC) Overview

The CS5381-KZZ is a 24-bit, multi-bit delta-sigma analog-to-digital converter designed for high-fidelity digital audio systems. It features a differential analog architecture with integrated anti-alias filtering, eliminating the need for external filters. The device supports sample rates up to 216 kHz per channel, achieving a dynamic range of 120 dB and -110 dB THD+N at 1 kHz. It operates with separate analog (5 V), digital (3.3–5 V), and logic (2.5–5 V) supplies. Key specifications include low-latency digital filtering, overflow detection, and pin compatibility with the CS5361.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix KZZ corresponds to the Commercial grade (-10°C to +70°C) variant in the 24-pin TSSOP or SOIC package. Confirm that the ordering information section of the official datasheet lists this specific suffix for the required temperature range and package type before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5381-KZZ when system requirements demand 120 dB dynamic range and support for sample rates up to 192 kHz. Ensure the design accommodates separate 5 V analog and 3.3–5 V digital/logic power supplies. Verify that the host processor can interface with the serial audio port in either Master or Slave mode using I²S or Left-Justified formats.

Analog To Digital Converters (ADC) Part Context

The CS5381 is part of Cirrus Logic's professional audio ADC family. It serves as a direct pin-compatible replacement for the CS5361, offering enhanced performance with higher dynamic range and support for faster sample rates. The device integrates the modulator, digital filter, and decimation logic into a single chip.

Analog To Digital Converters (ADC) Replacement Considerations

The CS5381 is pin-compatible with the CS5361. When replacing the CS5361, verify that the existing clocking scheme supports the higher speed modes if utilizing the full 192 kHz capability. No functional changes are required for basic 48 kHz operation.
