CS4332B Overview

The CS4332B is part of a new series of pro-audio converters aimed at giving cost-effective transparent audio conversion. All within one device that is easy to use and provides system level cost savings. The CS4332B is a high-performance, 32-bit resolution, two-channel DAC. The CS4332B supports differential analog outputs and 32-bit digital input via the audio serial port (ASP) at sample rates up to 384 kHz. The voltage-output CS4332B incorporates a proprietary analog FIR architecture to reduce out-of-band noise and minimize the external component requirements. This provides a dynamic range of over 110 dB and THD+N below -107 dB. The device can be powered from a single rail and controlled by either hardware pins, I2C or SPI, making it both flexible and easy to integrate. This, together with Cirrus Logic’s advanced digital filters, makes the CS4332B ideal for digital mixing consoles, DAW interfaces, effects processors, musical instruments and audio/video receivers.
