CS4334-KSZR

Digital To Analog Converters Overview

The CS4334-KSZR is a stereo digital-to-analog converter manufactured by Cirrus Logic Inc. It operates on a single +5 V power supply and supports sample rates from 2 kHz to 100 kHz. The device provides 24-bit resolution with a typical dynamic range of 96 dB (A-weighted) and -88 dB THD+N at 0 dBFS in Base-Rate Mode. It features an I²S serial interface, internal digital de-emphasis, and Popguard® technology for transient control. The component is housed in an 8-SOIC package and functions within an ambient temperature range of -10°C to +70°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix KZ or KZR against current manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as required by local regulations. Check for End-of-Life notifications or alternative part recommendations directly from the manufacturer before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a complete stereo DAC solution with minimal external support circuitry is required. Ensure the design utilizes a single +5 V supply and accommodates the 8-SOIC footprint. Verify that the host processor supports the I²S data format and can provide the necessary master clock ratios for the desired sample rate.

Digital To Analog Converters Part Context

This part belongs to the CS4334/5/8/9 family of devices. These components are functionally compatible regarding core performance but differ in supported serial data interfaces. The CS4334 specifically supports the I²S format, whereas other family members may support Left Justified or PCM modes.

Digital To Analog Converters FAQ

How does the CS4334 handle output transients?

It uses Popguard® technology, which clamps outputs to ground during startup and slowly ramps them to the quiescent voltage to prevent audible clicks.

What is the maximum input sample rate supported?

The device supports input sample rates up to 100 kHz when operating in High-Rate Mode.

Is digital de-emphasis available in all modes?

No, digital de-emphasis is only available in Internal Serial Clock Mode and is not supported in High-Rate Mode.
