UDA1338H  
Multichannel audio coder-decoder  
Rev. 03 — 16 February 2005  
Product data sheet  
1. General description  
The UDA1338H is a single-chip consisting of 4 plus 1 analog-to-digital converters and  
6 digital-to-analog converters 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 UDA1338H 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 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  
UDA1338H 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.  
2. Features  
2.1 General  
2.7 V to 3.6 V power supply  
5 V tolerant digital inputs  
24-bit data path  
Selectable control: via L3-bus or I2C-bus microcontroller interface  
Supports sample frequency ranges for:  
Audio ADC: fs = 16 kHz to 100 kHz  
Voice ADC: fs = 7 kHz to 50 kHz  
Audio DAC: fs = 16 kHz to 200 kHz  
Separate power control for ADC and DAC  
ADC plus integrated high-pass filter to cancel DC offset  
Integrated digital filter plus DAC  
Slave mode only applications  
Easy application
