GENERAL DESCRIPTION
The UDA1320ATS/N2 is a single-chip non inverting stereo DAC employing bitstream conversion techniques. The low power consumption and low voltage requirements make the device eminently suitable for use in digital audio equipment which incorporates playback functions.
FEATURES
General
• Low power consumption.
• 2.7 to 3.6 V power supply.
• Selectable control via L3 microcontroller interface or via static pin control.
• 256, 384 and 512fs system clock (fsys), selectable via the L3 interface or 256 and 384fs clock mode via static pin control
• supports sampling frequencies from 16kHz to 48kHz.
• Integrated digital filter plus non inverting DAC Digital-to-Analog Converter (DAC).
• Easy application and no analog post filtering required for DAC.
• Slave mode only applications.
• Small package size (SSOP16).
Multiple format input interface
• I2S-bus, MSB-justified and LSB-justified 16,18 and 20 bits format compatible (in L3-mode).
• I2S-bus and LSB-justified 16,18 and 20 bits format compatible in static mode.
• 1fs input format data rate.
DAC digital sound processing
• Digital logarithmic volume control via L3.
• Digital de-emphasis for 32, 44.1 and 48 kHz fs via L3 or 44.1 kHz fs via static pin control.
• Soft mute via static pin control or via L3 interface.
Advanced audio configuration
• Stereo line output (under L3 volume control)
• High linearity, wide dynamic range, low distortion.
APPLICATIONS
• Portable digital audio equipment, see Fig.8.
• Set-top boxes
