GENERAL DESCRIPTION
The UDA1343TT is a single-chip stereo Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC) with basic signal processing features employing bitstream conversion techniques. The low power consumption, the small package size 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.
