CS5330A-KS

ADCs/DACs - Special Purpose Overview

The CS5330A-KS 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 a typical power dissipation of 150 mW and includes a power-down mode. The output sample rate is 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

ADCs/DACs - Special Purpose Applications

• Digital audio systems requiring stereo A/D conversion
• Portable audio equipment utilizing the power-down mode
• Professional audio interfaces needing precise anti-alias filtering

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'KS' against the manufacturer's datasheet to confirm package type and temperature range specifications. Ensure compatibility with existing board layouts for the 8-pin SOIC package. Confirm that the single +5 V supply requirement aligns with the target system design before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when 18-bit stereo conversion is sufficient and a single +5 V supply is available. The integrated digital filtering simplifies design by removing the need for external analog anti-alias filters. Consider the adjustable sampling rate feature if flexible clocking is required for different audio standards.

ADCs/DACs - Special Purpose Part Context

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

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes include other variants within the CS5330A family, such as CS5330A-BS or CS5330A-KSR, provided the package and electrical characteristics match the application requirements.
