CS5330A-KSR

ADCs/DACs - Special Purpose Overview

The CS5330A-KSR is an 8-pin stereo analog-to-digital converter designed for digital audio applications. It integrates delta-sigma A/D converters, digital anti-alias filtering, sample-and-hold circuitry, and a voltage reference into a complete CMOS system. The device provides 18-bit resolution with a dynamic range of 94 dB. It operates on a single +5 V power supply with low power dissipation of 150 mW and includes a power-down mode. The output sample rate is infinitely adjustable between 2 kHz and 50 kHz, supporting standard rates such as 32 kHz, 44.1 kHz, and 48 kHz.

ADCs/DACs - Special Purpose Feature Summary

• 18-bit resolution with 94 dB dynamic range
• Integrated linear phase digital anti-alias filtering with -0.05 dB passband ripple and -80 dB stopband rejection
• Adjustable sampling rates from 2 kHz to 50 kHz, including 32 kHz, 44.1 kHz, and 48 kHz
• Single +5 V power supply operation with 150 mW power dissipation and power-down mode

ADCs/DACs - Special Purpose Applications

• Digital audio systems requiring stereo A/D conversion
• Portable audio equipment utilizing power-down capabilities
• Audio interfaces supporting variable sampling rates

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix KSR against official Cirrus Logic documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing board layouts for the 8-pin SOIC package. Confirm that the 150 mW power dissipation meets thermal requirements for the target application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component when 18-bit resolution and 94 dB dynamic range are sufficient for the audio chain. The integrated digital filter simplifies design by removing the need for external analog anti-alias filters. Verify that the required sampling rate falls within the 2 kHz to 50 kHz adjustable range. Consider the single +5 V supply constraint compared to lower voltage alternatives.

ADCs/DACs - Special Purpose Part Context

The CS5330A-KSR belongs to the CS5330A/31A family of stereo A/D converters. Variants such as CS5330A-BS and CS5330A-BSR share similar functional descriptions but may differ in packaging or reel configurations. The KSR suffix typically denotes a specific tape and reel quantity or package variant within the Cirrus Logic product line.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes include other CS5330A variants like CS5330A-BS or CS5330A-BSR, provided pinout and electrical characteristics remain identical. Cross-reference with CS5331A if mono channel functionality is acceptable. Verify that any replacement maintains the 18-bit resolution and 5 V supply requirement.
