GENERAL DESCRIPTION
The UDA1342TS is a single-chip 4 channel
analog-to-digital converter and 2 channel digital-to-analog
converter 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 UDA1342TS 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 24 bits and the LSB-justified
serial data format with word lengths of 16, 20 and 24 bits.
The device also supports a combination of the
MSB-justified output format and the LSB-justified input
format.
The UDA1342TS has special sound processing features in
the playback mode such as de-emphasis, volume, mute,
bass boost and treble, which can be controlled by the
microcontroller via the L3-bus or I2C-bus interface.
