CS4271K-DZZR Description

The CS4271K-DZZR is a high-performance stereo audio codec designed for demanding audio applications. Manufactured by Cirrus Logic Inc., this interface IC chip offers exceptional audio quality and versatility. It features a dynamic range of 108 dB for ADCs and 114 dB for DACs, ensuring superior audio clarity. The device operates with a digital supply voltage ranging from 3.1V to 5.25V and an analog supply voltage between 4.75V and 5.25V. It employs a serial data interface, making it suitable for applications where minimal pin count and board space are critical.

The CS4271K-DZZR includes two ADCs and two DACs, each with a resolution of 24 bits, providing detailed and accurate audio processing. The codec also incorporates sigma-delta technology, which enhances the signal-to-noise ratio (SNR) to 98 dB for ADCs and 100 dB for DACs. This high SNR ensures that the audio output is free from unwanted noise, delivering a pristine listening experience.

The device is available in a surface-mount package, specifically in a tape & reel (TR) format, making it ideal for automated assembly processes. It is classified under ECCN EAR99 and HTSUS 8542.39.0001. The CS4271K-DZZR is REACH unaffected and RoHS3 compliant, ensuring it meets stringent environmental and safety standards. It also has a moisture sensitivity level (MSL) of 3, which allows for a storage time of 168 hours before reflow soldering.
