The AD7845 is the industry's first four-quadrant multiply-to-analog converter with an on-chip amplifier. It is manufactured using the LC2MOS process and can integrate precision linear components and digital circuitry on the same chip.
12 data inputs can be driven by the standard.CSandWRSignal-controlled latches for easy interfacing with microprocessors. When working independently,.CSandWRThe inputs can be grounded, allowing all latches to operate transparently. All digital inputs are TTL and 5 V CMOS compatible.
The output amplifier can supply ±10 V into a 2 kΩ load. It is internally compensated and laser trimmed at the wafer level, resulting in a low input offset voltage. When working normally, RFBConnect to VOUT, but the user can also select RA、 RB or RCto adjust the output voltage range.
