CS5381-KSZR

Analog To Digital Converters (ADC) Overview

The CS5381-KSZR is a 24-bit stereo audio analog-to-digital converter (ADC) manufactured by Cirrus Logic. It utilizes an advanced multi-bit delta-sigma architecture to achieve a dynamic range of 120 dB and total harmonic distortion plus noise (THD+N) of -110 dB. The device supports output sample rates up to 216 kHz per channel, covering standard audio frequencies including 48 kHz, 96 kHz, and 192 kHz. It features differential analog inputs, an internal voltage reference, and a serial audio interface compatible with I²S and Left-Justified formats. The component operates on a 5 V analog supply and 3.3 V to 5 V digital/logic supplies, housed in a 24-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• 24-bit resolution with 120 dB dynamic range and -110 dB THD+N
• Supports sample rates from 2 kHz to 216 kHz via Single, Double, and Quad-Speed modes
• Integrated digital high-pass filter for DC offset removal or calibration
• Open-drain overflow detection output (OVFL) for signal monitoring

Analog To Digital Converters (ADC) Applications

• A/V receivers and home theater systems
• Digital mixing consoles and effects processors
• DVD-R and CD-R recording equipment
• High-fidelity audio digitization systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'KSZR' corresponds to the 24-pin SOIC package variant as defined in the manufacturer's ordering information. Confirm that the required logic voltage levels (VL) align with the system design, as the device supports both 5 V and 2.5 V logic interfaces. Ensure compliance with the specified operating temperature range of -10°C to +70°C for commercial grade applications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high dynamic range and low latency digital filtering are required for stereo audio conversion. The CS5381 eliminates the need for external anti-alias filters due to its integrated digital filtering. Designers must account for the differential input architecture and provide appropriate buffering if necessary. The choice between Master and Slave mode depends on the system clocking strategy, requiring configuration of M/S, M0, and M1 pins.

Analog To Digital Converters (ADC) Part Context

The CS5381 is part of Cirrus Logic's CS53xx series of audio ADCs. It is pin-compatible with the CS5361, facilitating potential upgrades or replacements in existing designs where slightly different performance characteristics might be needed. The KZZR suffix denotes the TSSOP package variant, while KSZR indicates the SOIC package.

Analog To Digital Converters (ADC) Replacement Considerations

The CS5361 is a pin-compatible alternative within the same family. Verify if the specific performance differences between the CS5381 and CS5361 meet the application requirements before substitution.
