AD7845是业界首款内置片内放大器的四象限乘法数模转换器。它采用LC2MOS工艺制造，可以在同一芯片上集成精密线性元件与数字电路。
The 12 data inputs drive a latch controlled by standard CS and WR signals, allowing for easy interfacing with the microprocessor. When working independently, the CS and WR 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 to a 2 kΩ load. It is internally compensated and laser-adjusted at the wafer level, resulting in a low input offset voltage. When operating normally, the RFB is connected to VOUT, but the user can also select RA, RB, or RC to adjust the output voltage range.
