Product Summary

The AD7847BR is a complete, dual, 12-bit multiplying digital-to-analog converter with output amplifiers on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. The output amplifier AD7847BR is capable of developing ±10V across a 2kΩ load. It is internally compensated with low input offset voltage due to laser trimming at wafer level. The amplifier feedback resistor AD7847ARZ is internally connected to VOUT on the AD7847.
