Cirrus Logic has introduced the CS5368, an analog-to-digital (ADC) audio converter integrated circuit (IC) that eliminates the need for incorporating multiple stereo analog-to-digital converters for surround-sound or multichannel applications. The audio ADC features a high-speed TDM interface, which provides a serial output of eight channels of audio data with sample rates up to 192 kHz within a single data stream. The company also offers the IC in pin-compatible four- and six-channel options (CS5364 and CS5366), providing an upgrade path. Each IC provides an 114 dB dynamic range and a low-noise measurement of –105 dB THD+N. The ICs also feature a differential architecture that provides noise rejection and performs sampling, analog-to-digital conversion and anti-alias filtering. Each IC also supports all common PCM and TDM audio formats.

Pricing and Availability

The CS5368/66/64, which are currently sampling to customers, are available in 48-pin LQFP packages and are priced at $11.61, $10.35, and $9.09, respectively, in quantities of 10,000.
