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 can withstand ESD
pulses of -2500 to +2500 V.
3. Equivalent to discharging a 200 pF capacitor via a 2.5 H series inductor.
4. Short-circuit test at Tamb = 0 °C and VDDA = 3 V. DAC operation after short-circuiting cannot be warranted.


Description

The UDA1324TS is a single-chip stereo DAC employing bitstream conversion techniques. The ultra low-voltage requirements make the device eminently suitable for use in portable digital audio equipment which incorporates playback functions.

The UDA1324TS 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 UDA1324TS can be used in two modes: 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 UDA1324TS can be operated in the 256fs and 384fs system clock mode. Muting, de-emphasis for 44.1 kHz and four digital input formats (I2S-bus or LSB-justified 16, 18 and 20 bits) can be selected via static pins. The L3 interface cannot be used in this application mode, so volume control is not available in this mode.
