Description

The UDA1384 is a single-chip consisting 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.

The UDA1384 supports conventional 2 channels per line data transfer conformable to the I2S-bus format with word lengths of up to 24 bits, the MSB-justified format with word lengths of up to 24 bits and the LSB-justified format with word lengths of 16 bits, 20 bits and 24 bits, as well as 4 channels to 6 channels per line transfer mode. The device also supports a combination of the MSB-justified output format and the LSB-justified input format. The UDA1384 has special sound processing features in the Direct Stream Digital (DSD) playback mode, de-emphasis, volume and mute which can be controlled via the L3-bus or I2C-bus interface.
