CS5351-KZZR

ADCs/DACs - Special Purpose Overview

The CS5351-KZZR is a 24-bit stereo audio analog-to-digital converter manufactured by Cirrus Logic. It utilizes an advanced multi-bit delta-sigma architecture to achieve a typical dynamic range of 108 dB and -98 dB THD+N at sampling rates up to 192 kHz per channel. The device integrates sampling, anti-alias filtering, and digital decimation, eliminating the need for external anti-alias filters. It operates with single-ended analog inputs and supports logic levels between 2.5 V and 5 V. The component is housed in a 24-pin TSSOP package and functions within a commercial temperature range of -10°C to +70°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix KZZR corresponds to the lead-free 24-pin TSSOP package with a commercial operating temperature range (-10°C to +70°C). Confirm that the ordering information matches the manufacturer's current datasheet revision, as older variants may exist. Ensure compatibility with the required power supply voltages (VA: 4.75V–5.25V) and logic levels before integration.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring wide dynamic range and negligible distortion without external anti-alias filtering. It is suitable for systems needing pin compatibility with the CS5361. Consider the single-ended input requirement and the internal high-pass filter characteristics when designing the analog front end. Verify master or slave mode clocking requirements against the system processor capabilities.

ADCs/DACs - Special Purpose Part Context

The CS5351 belongs to Cirrus Logic's family of multi-bit audio A/D converters. It shares pin compatibility with the CS5361 model. The device is designed for high-performance digital audio systems where low noise and high linearity are critical. It replaces older single-bit delta-sigma designs by offering superior performance through its multi-bit modulator architecture.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5361 is explicitly noted as pin-compatible with the CS5351. When substituting, verify that the dynamic range and THD+N specifications of the replacement meet the system requirements, as the CS5361 typically offers higher performance metrics.
