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.
3. Equivalent to discharging a 200 pF capacitor via a 2.5 H series inductor.
4. Short-circuit test at T_amb = 0 °C and V_DDA = 3 V. DAC operation after short-circuiting cannot be warranted.

Description

The UDA1330ATS is a single-chip stereo DAC employing bitstream conversion techniques.

The UDA1330ATS 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 UDA1330ATS can be used in two modes: L3 mode or the 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 UDA1330ATS can be operated in the 256f_s and 384f_s 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.
