CS4351-CZZ

ADCs/DACs - Special Purpose Overview

The CS4351-CZZ is a stereo digital-to-analog converter (DAC) from Cirrus Logic, featuring a fifth-order multi-bit delta-sigma modulator and 24-bit resolution. It supports sample rates up to 192 kHz and delivers a typical dynamic range of 112 dB with -100 dB THD+N. The device integrates a 2 Vrms line-level driver, digital volume control with soft ramp, and ATAPI mixing capabilities. It operates on +3.3 V, +9 to +12 V, and VL power supplies within a 20-pin TSSOP package, rated for commercial temperatures between -10°C and +70°C.

ADCs/DACs - Special Purpose Feature Summary

• Multi-bit Delta-Sigma Modulator: Provides ideal differential linearity and high tolerance to clock jitter.
• Integrated Line Driver: Outputs 2 Vrms into a 5 kΩ AC load without requiring external DC blocking capacitors.
• Digital Volume Control: Offers 119 dB attenuation with 1/2 dB step size and zero-crossing click-free transitions.
• Popguard Technology: Controls clicks and pops during power-up and power-down sequences.

ADCs/DACs - Special Purpose Applications

• DVD players
• A/V receivers
• Set-top boxes
• Digital TVs
• Mixing consoles

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CZZ' confirms the commercial temperature grade (-10°C to +70°C). Confirm the package type is 20-pin TSSOP. Check for RoHS compliance status in current distributor listings as manufacturing statuses may change.

ADCs/DACs - Special Purpose Selection Notes

Select this component for cost-sensitive 2-channel audio systems requiring high performance. Ensure the design accommodates the three separate power supplies (+3.3 V, +9 to +12 V, and VL). Verify that the serial interface format (I2S, Left-Justified, or Right-Justified) matches the source data stream requirements.

ADCs/DACs - Special Purpose Part Context

The CS4351 belongs to Cirrus Logic's family of complete stereo DAC systems. It includes digital interpolation, de-emphasis, and analog filtering on-chip. The CDB4351 demonstration board is available for evaluation. Similar parts in the series include the CS4350, CS4352, and CS4353.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements are not explicitly listed in the provided documentation. Consider the CS4352 or CS4353 for similar functionality but verify pin compatibility and power supply requirements carefully before substitution.
