APPLICATIONS
GENERAL DESCRIPTION
The UDA1343TT is a single-chip stereo Analog-to-Digital
Converter (ADC) and Digital-to-Analog Converter (DAC)
with basic signal processing features employing bitstream
conversion techniques. The low power consumption, the
small package size 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 UDA1343TT is equipped with a digital mixer for mixing
the ADC signal directly to the playback signal (for example
for Karaoke applications). In the mixing mode the ADC
output signal can be output before or after the mixer.
The mixer can also be used as a selector to select
between the ADC or the digital data being played back at
the DAC.
PACKAGE
High linearity, dynamic range and low distortion
Digital silence detector
Digital mixer for mixing ADC signal and playback signal
ADC volume control in 0.25 dB steps and cosine roll-off
mute.
Portable equipment which includes audio functions
Digital video camera.
