Description

The UDA1380TT is a single-chip electronic component model in the interface - CODECs product category. It consists of 4 plus 1 Analog-to-Digital Converters (ADC) and 6 Digital-to-Analog Converters (DAC) with signal processing features employing bitstream conversion techniques. The multichannel configuration makes the device eminently suitable for use in digital audio equipment which incorporates surround feature.
