The PD63210 is a 16-bit dual D/A converter IC for digital audio demodulation, which incorporates an 8-times oversampling digital filter and operational amplifiers for analog post filters. With few external parts and an easy substrate design (as to 1-bit D/A), it is suitable for multimedia terminals, MPEG audio equipment, video CDs, game machines, and electronic musical instruments, etc. To cope with sets for portable applications, a low-voltage operating version PD63210L (lowest operating supply voltage = +3.0 V) is also available.
