Incorporated into the PCM1702 is an advanced sign magnitude architecture that eliminates unwanted glitches and other nonlinearities around bipolar zero. The PCM1702 also features a very low noise (120dB typ SNR: A-weighted method) and fast settling current output (200ns typ, 1.2mA step) which is capable of 16X oversampling rates. Applications include very low distortion frequency synthesis and high-end consumer and professional digital audio applications. q CAPABLE OF 16X OVERSAMPLING q COMPLETE WITH REFERENCE q LOW POWER (150mW typ) Clock Data LE DCOM ACOM +VCC –VCC Input Shift Register and Control Logic Balanced Current Segment DAC A Balanced Current Segment DAC B Reference and Servo Bipolar Offset IOUT RF DC SERV DC BPO DC International Airport Industrial Park Mailing Address: PO Box 11400 Tel: (520) 746-1111 Twx: 910-952-1111 Cable: BBRCORP © 1993 Burr-Brown Corporation Tucson, AZ 85734 Street Address: 6730 S.
