DESCRIPTION

The UDA1341TS is a single-chip stereo Analog-to-Digital
Converter (ADC) and Digital-to-Analog Converter (DAC)
with signal processing features employing bitstream
conversion techniques. Its fully integrated analog front
end, including Programmable Gain Amplifier (PGA) and a
digital Automatic Gain Control (AGC). Digital Sound
Processing (DSP) featuring makes the device an excellent
choice for primary home stereo MiniDisc applications, but
by virtue of its low power and low voltage characteristics it
is also suitable for portable applications such as MD/CD
boomboxes, notebook PCs and digital video cameras.
The UDA1341TS is similar to the UDA1340M and the
UDA1344TS but adds features such as digital mixing of
two input signals and one channel with a PGA and a digital
AGC.
The UDA1341TS supports the I
word lengths of up to 20 bits, the MSB-justified data format
with word lengths of up to 20 bits, the LSB-justified serial
data format with word lengths of 16, 18 and 20 bits and
three combinations of MSB data output combined with
LSB 16, 18 and 20 bits data input. The UDA1341TS has
DSP features in playback mode like de-emphasis, volume,
bass boost, treble and soft mute, which can be controlled
via the L3-interface with a microcontroller.
PACKAGE
Optional differential input configuration for enhanced
ADC sound quality
Stereo line output (under microcontroller volume
control)
Digital peak level detection
High linearity, dynamic range and low distortion.
