GENERAL DESCRIPTION
The SAA7360 is a CMOS ADC using Philips bitstream
conversion technique. The device is designed for digital
audio playback systems, such as digital amplifiers,
CD-recordable and Digital Compact Cassette (DCC). The
device is a complementary device to the SAA7350
bitstream conversion digital-to-analog converter (DAC).
