CS5340-CZZ

ADCs/DACs - Special Purpose Overview

The CS5340-CZZ is a dual-channel, 24-bit audio analog-to-digital converter (ADC) utilizing an advanced multi-bit delta-sigma architecture. It integrates sampling, anti-alias filtering, and digital conversion to generate serial 24-bit data for left and right channels at sample rates up to 200 kHz per channel. The device operates with analog and digital core supplies ranging from 3.3 V to 5 V, while supporting logic levels between 1.8 V and 5 V. Key electrical specifications include a typical dynamic range of 101 dB at 5 V and a total harmonic distortion plus noise (THD+N) of -94 dB. Power consumption is typically 90 mW under normal operation conditions.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. The 'C' designation indicates the commercial operating temperature range of -10°C to +70°C. Ensure that the source document explicitly lists the CS5340-CZZ as available; do not assume availability based on similar part numbers or generic family listings.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring wide dynamic range and negligible distortion in digital audio systems. The device supports both clock master and slave modes, with automatic speed mode detection in slave configurations. Verify that the system's master clock frequency aligns with the required MCLK/LRCK ratios (e.g., 256x, 512x) for the desired output sample rate. Ensure power supply decoupling follows the recommended layout to maintain performance.

ADCs/DACs - Special Purpose Part Context

The CS5340 is part of Cirrus Logic's multi-bit audio ADC family, designed for high-performance digital audio processing. It is pin-compatible with the CS5341, facilitating potential design upgrades or replacements within existing layouts. The device eliminates the need for external anti-alias filters through its integrated digital filtering capabilities.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5341 is documented as pin-compatible with the CS5340. Verify functional equivalence and parameter differences via official datasheets before substitution.
