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, except pin 14 which must be specified to
-2500V (MIN) and +2500V (MAX).
3. Equivalent to discharging a 200 pF capacitor via a 2.5 H series inductor.


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.

The UDA1320ATS/N2 supports the I2S-bus data format with word lengths of up to 20 bits, the MSB-justified data format with word lengths of up to 20 bits and the LSB-justified serial data format with word lengths of 16, 18 and 20 bits.

The UDA1320ATS/N2 can be used in two modes, either L3-mode or static pin mode.

In the L3-mode, all digital sound processing features must be controlled via the L3 interface, including the selection of the system clock setting.

In the two static-modes, the UDA1320ATS/N2 can be operated in the 256fs and 384fs system clock mode. The mute, de-emphasis for 44.1 kHz and 4 digital input formats (I2S and 16, 18, 20 bits LSB formats) can be selected via static pins. The L3 interface cannot be used in this application mode, also, volume control is not available in this mode.
