The CS5344 is a cost-effective, complete audio A/D converter targeting value-line consumer and automotive digital audio systems. They perform sampling, A/D conversion and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 108 kHz per channel and deliver 98 dB of dynamic range and -92 db of THD + N. The CS5343/4 uses a third-order, multibit Delta-Sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter. Furthermore, integrated audio input buffers support passive analog input circuits, which simplifies design and reduces external component costs. Consuming only 36 mW of power, the ICs operate from a single power supply and support voltages from 3.3 V to 5 V and incorporate a unique input architecture which provides a very high input impedance of 7.5 M ohm. They differ only in serial audio interface format support, with the CS5343 supporting the I²S format and the CS5344 supporting left-justified serial data format. The CS5343/4 is available in a very small, space-saving 10-pin TSSOP (3 mm X 3 mm) package and is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as set-top boxes, DVD-karaoke players, DVD recorders, A/V receivers, effects processors and automotive applications.
