CS5381K-KZZ

Analog To Digital Converters (ADC) Overview

The CS5381K-KZZ is a 24-bit stereo audio analog-to-digital converter from Cirrus Logic, housed in a 24-pin TSSOP package. It utilizes an advanced multi-bit delta-sigma architecture to achieve a dynamic range of 120 dB and -110 dB THD+N. The device supports output sample rates up to 216 kHz across single, double, and quad-speed modes. It features differential analog inputs, an internal voltage reference, and a serial audio interface compatible with I²S and Left-Justified formats. Operating conditions include an analog supply of 5 V (4.75–5.25 V) and digital/logic supplies of 3.3 V to 5 V.

Analog To Digital Converters (ADC) Feature Summary

• 24-bit resolution with 120 dB dynamic range and -110 dB THD+N
• Supports sample rates up to 216 kHz via Single, Double, and Quad-Speed modes
• Integrated linear phase digital anti-alias filter and high-pass filter for DC offset removal
• Differential analog input architecture with overflow detection capability

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix KZZ corresponds to the 24-pin TSSOP commercial grade package (-10°C to +70°C). Confirm power supply requirements: VA at 5 V nominal, VD and VL between 3.3 V and 5 V. Ensure system clocking aligns with Master or Slave mode configurations as defined in the datasheet tables.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low distortion without external anti-alias filters. Choose Master Mode if on-chip LRCK and SCLK generation is needed; otherwise, use Slave Mode for external clock synchronization. Consider the OVFL pin configuration for overrange detection if signal clipping monitoring is required.

Analog To Digital Converters (ADC) Part Context

The CS5381 is part of Cirrus Logic's high-performance audio ADC family. It is pin-compatible with the CS5361, facilitating design upgrades or replacements within existing layouts. The device integrates switch-capacitor ADCs and digital filters to simplify system design by eliminating external filtering components.

Analog To Digital Converters (ADC) Replacement Considerations

The CS5361 is a pin-compatible alternative within the same series. Verify that the target application's performance requirements align with the CS5361 specifications before substitution.
