GENERAL DESCRIPTION
The UDA1340 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 UDA1340 supports the I
2
S-bus data format with word
lengths of up to 20 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 UDA1340 has special sound processing features in
playback mode, de-emphasis, volume, bass boost, treble,
and soft mute, which can be controlled via the
microcontroller interface.
