GENERAL DESCRIPTION
The UDA1360TS is a single chip stereo Analog-to-Digital
Converter (ADC) employing bitstream conversion
techniques. The low power consumption and low voltage
requirements make the device eminently suitable for use
in low-voltage low-power portable digital audio equipment
which incorporates recording functions.
The UDA1360TS supports the I2S-bus data format and the
MSB-justified data format with word lengths of up to
20 bits.
