Description



Features:

1 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.
2 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.
3 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.
4 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.


Application

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

Notes
1. All supply connections must be made to the same power supply.
2. Equivalent to discharging a 100 pF capacitor via a 1.5 k series resistor, expect pin 19 (L3DATA) which can
withstand ESD pulses of -2500 to +2500 V.
3. Equivalent to discharging a 200 pF capacitor via a 0.75H series inductor.



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.

The UDA1328 supports the I2S-bus data format with word lengths of up to 24 bits, the MSB-justified data format with word lengths of up to 24 bits and the LSB-justified serial data format with word lengths of 16, 18, 20 and 24 bits.

All digital sound processing features of UDA1328 can be controlled with  the L3 interface e.g. volume control, selecting digital silence type, output polarity control and mute. Also system features such as power control, digital silence detection mode and output polarity control.

Under static pin control, via static pins, the UDA1328 system clock can be set to either 256fs or 384fs support, digital de-emphasis can be set, there is digital mute and the digital input formats can also be set.
