CS5351K-DZZ

ADCs/DACs - Special Purpose Overview

The CS5351K-DZZ is a 24-bit, multi-bit delta-sigma analog-to-digital converter designed for digital audio systems. It supports sampling rates up to 192 kHz per channel and delivers a typical dynamic range of 108 dB with -98 dB THD+N. The device integrates anti-alias filtering via a 5th-order modulator and digital decimation, eliminating the need for external filters. It features single-ended analog inputs, high-pass filter calibration, and overflow detection. Operating in the automotive temperature range (-40°C to 85°C), it consumes 135 mW at 3.3V logic levels and interfaces via serial audio ports compatible with I2S and Left-Justified formats.

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix 'DZZ' confirms the -40°C to 85°C automotive operating temperature range and 24-pin TSSOP package. Confirm lead-free status as specified in the ordering information. Ensure supply voltages match the specified ranges: VA 4.75–5.25 V, VD 3.1–5.25 V, and VL 2.37–5.25 V. Check pin compatibility if replacing legacy components like the CS5361.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring wide dynamic range and low distortion without external anti-alias filters. Choose the DZZ variant for environments exceeding commercial temperature limits (-10°C to 70°C). Ensure the host system supports the required master clock frequencies (e.g., 12.288 MHz for 48 kHz Fs) or slave mode clock ratios. Verify that single-ended analog inputs are sufficient for the source impedance.

ADCs/DACs - Special Purpose Part Context

The CS5351K-DZZ belongs to the CS5351 family of multi-bit audio ADCs. It is pin-compatible with the CS5361, facilitating direct upgrades or replacements in existing designs. The KZZ variant offers a commercial temperature range, while the DZZ variant extends operation to automotive temperatures. Both share identical electrical characteristics and pinouts.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5351K-KZZ is a verified substitute with identical functionality but a restricted commercial temperature range (-10°C to 70°C). No other cross-model substitutes are documented in the provided datasheet.
