Cirrus Logic CS4352 Digital-to-Analog Audio Converter Simplifies Designs, Cuts System Costs
With the introduction of the CS4352 digital-to-analog converter (DAC), Cirrus Logic Inc. has developed a highly competitive converter that offers a strong combination of audio performance and feature integration.
With its on-chip line-driver and analog low-pass filter, the CS4352 gives designers of mainstream consumer audio products, such as flat-panel digital televisions, DVD recorders, set-top boxes, game consoles and sound cards, the ability to eliminate external components, reduce design complexity and overall system costs.
Specifically, the on-chip line driver and analog low-pass filter directly drives a 2Vrms consumer line level audio output, eliminating the need for an operational amplifier and as many as 10 passive components within system designs. The integration and ability to directly drive the output of the end product greatly simplifies analog output stages and reduces costs. Automatic sample-rate detection, which uses proprietary Cirrus Logic techniques, further simplifies designs by automatically configuring the CS4352 into the appropriate operational mode.
The CS4352 utilizes a multibit Delta-Sigma architecture, operates from a 9 V or 12 V power supply and is hardware configurable. It is also pin-compatible with Cirrus Logic’s CS4351 DAC, ensuring an easy upgrade path for existing customers, and also features Cirrus Logic’s Popguard® technology for control of clicks and pops during power cycling.
The CS4352 is available in a 20-pin, lead-free TSSOP package and is currently sampling to customers. The CS4352 is priced at $1.60 in quantities of 10,000.
