CS4354-CSZ

ADCs/DACs - Special Purpose Overview

The CS4354-CSZ is a stereo digital-to-analog converter (DAC) from Cirrus Logic, designed for 5 V systems with a 2 VRMS ground-centered output. It integrates digital interpolation, third-order multi-bit delta-sigma conversion, digital de-emphasis, analog filtering, and an on-chip line-level driver. The device features a 101 dB A-weighted dynamic range and -86 dB THD+N. It supports sample rates up to 192 kHz via a 24-bit I²S interface. Power consumption is typically 50 mW. The component operates within a commercial temperature range of –40°C to +85°C and is housed in a lead-free 14-pin SOIC package.

ADCs/DACs - Special Purpose Feature Summary

• Advanced multibit delta–sigma modulator providing 101 dB A-weighted dynamic range and –86 dB THD+N
• Single-ended ground-centered analog architecture eliminating the need for DC-blocking capacitors
• Integrated inverting charge pump generating negative supply for filtered line-level outputs
• Low-latency digital filtering supporting input sample rates up to 192 kHz

ADCs/DACs - Special Purpose Applications

• Blu-Ray Disc players
• DVD players
• Set-top boxes
• Digital TVs
• DAB/DMB devices

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and environmental grade. Ensure that the required demonstration board, such as the CDB4354, is sourced separately if device evaluation or implementation guidance is needed during the design phase.

ADCs/DACs - Special Purpose Selection Notes

Select this component for cost-sensitive two-channel audio systems requiring a single 5 V analog supply. The integrated charge pump simplifies design by removing external DC-blocking capacitors. Verify that the host system provides a valid MCLK, LRCK, and SCLK ratio for the desired operational mode auto-detection.

ADCs/DACs - Special Purpose Part Context

The CS4354 is part of Cirrus Logic's stereo DAC family, specifically engineered for consumer electronics. It utilizes a third-order multi-bit delta-sigma architecture to achieve ideal differential linearity and high tolerance to clock jitter. The device is available in a commercial grade (-40°C to +85°C) within a 14-pin SOIC package.
