Cirrus Logic has introduced two stereo analog-to-digital converters (ADCs) targeted for consumer and automotive audio applications such as set-top boxes, digital televisions, DVD recorders, audio/video receivers, in-car entertainment and concierge systems and musical instruments. Based on an advanced multibit Delta-Sigma architecture, the CS5343 and CS5344 operate from a single 3.3V or 5V power supply and utilize a proprietary automatic mode selection to eliminate external configuration. These parts also incorporate a input architecture which provides a input impedance of 7.5 MOhms, giving designers improved flexibility to use simple passive input circuits for the stereo line-level inputs, thus reducing design time, board space and cost. The CS5343 and CS5344 support audio sample rates up to 108 kHz and deliver 98 dB of dynamic range and -90 dB of THD+N. Consuming only 50 mW of power, the CS5343 and CS5344 differ only in the serial audio interface format they support, with the CS5343 supporting the I²S format and the CS5344 supporting left-justified serial data format. The CS5343 and CS5344 are available in a 10-pin, lead-free TSSOP package and are each priced at $1.35 in quantities of 10,000.
