The UDA1345TS 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 that incorporates recording and playback functions.
The UDA1345TS supports the I²S-bus data format with word lengths of up to 24 bits, the MSB justified data format with word lengths of up to 20 bits and the LSB justified serial data format with word lengths of 16, 18 and 20 bits.
The UDA1345TS also supports three combined data formats with MSB justified data output and LSB 16, 18 and 20 bits data input.
The UDA1345TS can be used either with static pin control or under L3 microcontroller interface. In L3 mode the UDA1345TS has basic sound features in playback mode such as de-emphasis, volume control and soft mute.
