描述 Description

DESCRIPTION
The μPD63210 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 μPD63210L (lowest operating supply voltage = +3.0 V) is also available.FEATURES
? 16-bit resistor string D/A converter (2-channel) adopted
? S/N = 104 dBTYP.; DR = 96 dBTYP. (when VDD = 5.0 V)
? High-performance 8-times oversampling digital filter incorporated
? Pass band ripple : ±0.003 dB
?? Stop band rejection : 90 dB
? System clock 384/512fs selectable
? Serial input data format selectable
Format for 2’S compliment, MSB first, and backward justification data accommodated;
Input can be selected between 16- and 18 bits
? Full line of low-voltage operating products (μPD63210L)
? μPD63210 : VDD = 4.5 to 5.5 V
? μPD63210L : VDD = 3.0 to 5.5 V
? Wide operating temperature range (TA = –40 to +85 °C)
? Operational amplifier (2-channel) for D/A converter output incorporated
? Operational amplifier (2-channel) for post filter (LPF) configuration incorporated
? Digital de-emphasis function (fs = 32/44.1/48 kHz) incorporated
? Soft mute function incorporated
? CD double-speed playback function (when μPD63210: 384fs)
? 28-pin plastic SOP (375 mil) adopted
