CS5330A-KSZ

Analog To Digital Converters (ADC) Overview

The CS5330A-KSZ is an 8-pin stereo analog-to-digital converter designed for digital audio applications. It operates from a single +5 V supply with typical power dissipation of 150 mW and supports adjustable sampling rates between 2 kHz and 50 kHz, including standard frequencies of 32, 44.1, and 48 kHz. The device provides 18-bit resolution with a dynamic range of 94 dB. It integrates delta-sigma modulation, digital anti-alias filtering, sample-and-hold circuitry, and an internal voltage reference within a complete CMOS system.

Analog To Digital Converters (ADC) Feature Summary

• 18-bit resolution with 94 dB dynamic range
• Integrated linear phase digital anti-alias filter with 0.05 dB passband ripple and >80 dB stopband rejection
• Single +5 V power supply operation with 150 mW typical power consumption
• Adjustable output sample rate from 2 kHz to 50 kHz

Analog To Digital Converters (ADC) Applications

• Digital audio systems requiring low power consumption
• Battery-powered portable audio equipment
• Stereo analog-to-digital conversion interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package variant against the ordering information table in the datasheet. The -KSZ suffix indicates the commercial grade (-10°C to +70°C) in an 8-SOIC package. Confirm whether bulk or tape & reel packaging is required, as these are listed as distinct order numbers (CS5330A-KSZ vs CS5330A-KSZR). Ensure the application environment temperature falls within the specified commercial operating range.

Analog To Digital Converters (ADC) Selection Notes

Select the CS5330A-KSZ when an 18-bit stereo ADC with integrated digital filtering is required. This part differs from the CS5331A only in its serial data output format; the CS5330A outputs MSB on the LRCK transition, whereas the CS5331A is I²S compatible. Choose this component if the system design accommodates the specific timing requirements shown in Figure 2 of the datasheet.

Analog To Digital Converters (ADC) Part Context

The CS5330A is part of the CS5330A/31A family of stereo A/D converters manufactured by Cirrus Logic. It utilizes a 128x oversampling delta-sigma architecture to achieve high performance without external anti-alias filters. The device is functionally identical to the CS5331A except for the serial data interface timing.

Analog To Digital Converters (ADC) Replacement Considerations

The CS5331A-KSZ is a pin-compatible alternative that offers an I²S compatible serial data interface instead of the CS5330A's native format. Automotive grade equivalents include the CS5330A-BSZ and CS5330A-BSZR for extended temperature ranges.
