AD7847ARZ Datasheet PDF - ADI

The AD7847ARZ is a complete dual 12-bit multiplying Digital-to-analog Converter (DAC) with output amplifiers on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. It is microprocessor compatible with high speed data latches and interface logic. The AD7847 accepts 12-bit parallel data which is loaded into the respective DAC latch using the WR input and a separate chip select input for DAC. The AD7837 has a double-buffered 8-bit bus interface structure with data loaded to the respective input latch in two write operations. An asynchronous LDAC signal on the AD7837 updates the DAC latches and analog outputs. The output amplifiers are capable of developing ±10V across a 2kR load. It is internally compensated with low input offset voltage due to laser trimming at wafer level. It is fabricated in linear compatible CMOS, an advanced, mixed technology process that combines precision bipolar circuits with low power CMOS logic.
