Description

General part information

AD7845 Series

The AD7845 is the industry's first 4-quadrant multiplying D/A converter with an on-chip amplifier. It is fabricated on the LC2MOS process, which allows precision linear components and digital circuitry to be implemented on the same chip.The 12 data inputs drive latches which are controlled by standard CS andWRsignals, making microprocessor interfacing simple. For stand-alone operation, theCSandWRinputs can be tied to ground, making all latches transparent. All digital inputs are TTL and 5 V CMOS compatible.The output amplifier can supply ±10 V into a 2k(ohm) load. It is internally compensated, and its input offset voltage is low due to laser trimming at wafer level. For normal operation, RFBis tied to VOUT, but the user may alternatively choose RA, RBor RCto scale the output voltage range.
