UDA1345TS

Economy audio CODEC

GENERAL DESCRIPTION

The is a single-chip stereo Analog-to-Digital Converter ADC and Digital-to-Analog Converter DAC with signal processing features employing bitstream conversion techniques. The low power consumption and low voltage requirements make the device eminently suitable for use in low-voltage low-power portable digital audio equipment which incorporates recording and playback functions.
