GENERAL DESCRIPTION
The UDA1328 is a single-chip 6-channel DAC employing bitstream conversion techniques, which can be used either in L3 microcontroller mode or in static pin mode.

FEATURES
General
• 2.7 to 3.6 V power supply
• 5 V tolerant TTL compatible inputs
• Selectable control via L3 microcontroller interface or via static pin control
• Multi-channel integrated digital filter plus non-inverting Digital-to-Analog Converter (DAC)
• Supports sample frequencies between 5 and 100 kHz
• Digital silence detection (output)
• Slave mode only applications
• No analog post filtering required for DAC
• Easy application.

Multiple format input interface
• I2S-bus, MSB-justified and LSB-justified format compatible (in L3 mode)
• I2S-bus and LSB-justified format compatible
• 1fs input format data rate.

Multi-channel DAC
• 6-channel DAC with power on/off control
• Digital logarithmic volume control via L3; volume can be set for each of the channels individually
• Digital de-emphasis for 32, 44.1, 48 and 96 kHz fs via L3 and, for 32, 44.1 and 48 kHz in static mode
• Soft or quick mute via L3
• Output signal polarity control via L3 microcontroller interface.

Advanced audio configuration
• 6-channel line output (under L3 volume control)
• A stereo differential output (channel 1 and channel 2) for improved performance
• High linearity, wide dynamic range, low distortion.

APPLICATIONS
    This multi-channel DAC is eminently suitable for DVD like applications in which 5.1 channel encoded signals are used.
