UPD63210L

DATA SHEET µPD63210,63210L 16-BIT D/A CONVERTER WITH BUILT-IN DIGITAL FILTER FOR AUDIO MOS INTEGRATED CIRCUIT 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...
