The 10-pin CS5343 and CS5344 series of ADCs give OEMs an ultra-small (less than 15mm2), stereo-audio-data-conversion solution, capable of delivering superior sound quality. The devices are targeted at a variety of 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 multi-bit delta-sigma architecture, they operate from a single 3.3 or 5V power supply and use a proprietary automatic mode selection to eliminate external configuration. These parts also incorporate a unique input architecture, which provides an input impedance of 7.5mOhms, giving designers improved flexibility to use simple passive input circuits for the stereo line-level inputs, thus reducing design time, board space and cost.
