GENERAL DESCRIPTION
The UDA1344TS 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.
The UDA1344TS supports the I
word lengths of up to 20 bits, the MSB-justified data format
with word lengths of up to 20 bits and the LSB-justified
data format with word lengths of 16, 18 and 20 bits. The
UDA1344TS also supports three combined data formats
with MSB-justified data output and LSB-justified
16, 18 and 20 bits data input.
The UDA1344TS can be controlled either via static pins or
via the L3 interface. In the L3 mode the UDA1344TS has
special Digital Sound Processing (DSP) features in
playback mode such as de-emphasis, volume control,
bass boost, treble and soft mute.
PACKAGE
Stereo single-ended input configuration
Stereo line output (under microcontroller volume
control), no post filter required
High linearity, dynamic range and low distortion.
