CS5351-KSZ

ADCs/DACs - Special Purpose Overview

The CS5351-KSZ is a 24-bit, stereo analog-to-digital converter (ADC) designed for digital audio systems. It utilizes an advanced multi-bit delta-sigma architecture with a 5th-order modulator and digital filtering to perform sampling, conversion, and anti-aliasing without external filters. The device supports system sampling rates up to 192 kHz per channel and delivers a typical dynamic range of 108 dB with -98 dB THD+N. It features single-ended analog inputs, a high-pass filter for DC offset calibration, and overflow detection. The component operates on separate analog (VA), digital (VD), and logic (VL) supplies ranging from 2.5 V to 5.25 V and is housed in a 24-pin SOIC package.

ADCs/DACs - Special Purpose Feature Summary

• Supports sampling rates up to 192 kHz using multi-bit delta-sigma modulation
• Integrated high-pass filter and DC offset calibration circuitry
• Single-ended analog inputs with overflow detection output

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix KSZ indicates the commercial temperature range (-10°C to +70°C) and 24-pin SOIC package. Confirm RoHS compliance status as lead-free variants are designated by K or D suffixes. Check current availability as older audio ADC models may have limited stock or end-of-life status from distributors.

ADCs/DACs - Special Purpose Selection Notes

Select the CS5351-KSZ when single-ended analog inputs are required rather than differential architectures found in pin-compatible counterparts like the CS5361. Ensure the application requires a maximum sample rate of 192 kHz; higher rates require different models. Verify that the system clocking requirements align with the internal master clock divider capabilities if operating in master mode.

ADCs/DACs - Special Purpose Part Context

The CS5351 belongs to Cirrus Logic's multi-bit audio A/D converter family. It is pin-compatible with the CS5361, which offers differential inputs and slightly higher dynamic range (114 dB). The CS5351 distinguishes itself by supporting single-ended inputs, simplifying front-end design for applications where differential signaling is not utilized.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5361 is a pin-compatible alternative offering differential inputs and 114 dB dynamic range. For extended temperature ranges, the CS5351-DZZ provides automotive-grade operation (-40°C to +85°C) in a TSSOP package.
