CS4345-CZZ

ADCs/DACs - Special Purpose Overview

The CS4345-CZZ is a stereo digital-to-analog converter featuring 24-bit resolution and support for sample rates up to 192 kHz. It utilizes a fourth-order multi-bit delta-sigma modulator with an integrated linear analog low-pass filter. The device operates on a single +3.3 V or +5 V supply and accepts Left Justified serial audio data formats. Key performance metrics include a typical dynamic range of 105 dB (A-weighted) and -90 dB THD+N. It incorporates Popguard technology for output transient control and on-chip digital de-emphasis.

ADCs/DACs - Special Purpose Feature Summary

• Multi-bit Delta-Sigma Modulator with 24-bit resolution
• Automatic detection of sample rates from 2 kHz to 200 kHz
• Integrated analog low-pass filter and digital de-emphasis
• Popguard technology for click and pop suppression

ADCs/DACs - Special Purpose Applications

• DVD players and recorders
• Digital televisions
• Home theater systems
• Set-top boxes
• Automotive audio systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix '-CZZ' indicates the commercial temperature grade (-10°C to +70°C). Confirm the interface format matches the system requirement, as the CS4345 family supports Left Justified data. Check for automotive variants if operating conditions require extended temperature ranges.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring a single-supply stereo DAC with high dynamic range. Ensure the host processor supports the Left Justified serial interface format. Verify that the power supply voltage aligns with the specified +3.3 V or +5 V nominal levels. Consider the 10-pin TSSOP package constraints for PCB layout.

ADCs/DACs - Special Purpose Part Context

The CS4345-CZZ belongs to the CS4344/5/8 family of stereo DACs. Devices in this family share identical internal architecture and pinouts but differ in supported serial audio data formats. The CS4345 specifically supports Left Justified format, distinguishing it from the I2S-compatible CS4344 and Right Justified CS4348.

ADCs/DACs - Special Purpose Replacement Considerations

Direct functional replacements within the same family include CS4344-CZZ (I2S format) and CS4348-CZZ (Right Justified format), provided the digital interface protocol is compatible. For automotive temperature grades, consider the -DZZ suffix variants.
