UDA1330ATS/N2,112

The UDA1330ATS/N2,112 is a single-chip 20-bit stereo Digital-to-analog Converter (DAC) employing bit stream conversion techniques. The UDA1330ATS supports the I²S-bus data format with word lengths of up to 20-bit, the MSB-justified data format with word lengths of up to 20-bit and the LSB-justified serial data format with word lengths. 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 256fs and 384fs system clock mode. Muting, de-emphasis for 44.1KHz and four digital input formats 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.
