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.

FEATURES
General
• Low power consumption
• 2.4 V to 3.6 V power supply range, with 3 V typical
• 5 V tolerant TTL compatible digital inputs
• 256, 384 and 512fs system clock
• Supports sampling frequencies from 8 to 110 kHz
• Non-inverting ADC plus integrated high-pass filter to cancel DC offset
• The ADC supports 2 V (RMS) input signals
• Stereo PGA with 0 to 24 dB gain in 3 dB steps
• Overload detector for easy record level control
• Separate power control for ADC + PGA and DAC
• Integrated digital interpolation filter plus non-inverting DAC
• Functions controllable by L3 microcontroller interface
• Small package size (TSSOP28)
• ADC and DAC output polarity can be set.

APPLICATIONS
• Portable equipment which includes audio functions
• Digital video camera.
