NAME TYPE DESCRIPTION 1 AGND The currcnt from the digital input are switched between the DAC OUTPUT and AGND thus maintaining fixed currcnt in cach ladder leg. Independent of switch statc. 2 OUT A O 20 OUT B O Analog data is restored from D/A conveter which the digital data is transferred ino ether of the two DAC. 3 19 R FB A R FB A Internal feedback resistor 4 18 V REF A R REF B The refercnce voltage for the R-2R ladder structure DAC. 5 DGND 6 DAC A/D ACB I Both DAC latchcs sharc a common s-bit input port. The control input DAC A/D ACB selects which DAC can accept data from the input port. 7-14 DB7-DB0 I Data bus is TTL./CMOS com -patible. Data is transferred into the either of two latches of DAC. DB0 is the least significant bit 15 CS I Input CS and WR control the operating mode of the selectod DAC. When CS and WR are both ow. The sclected DAC is in the Write mode. The input dath latches of the sclectod DAC are transparcnt and its analog output responds to activity on DB0-DB7 17 VDD Power |
