AD7237 Datasheet PDF

●The AD7237JNZ is a dual 12-bit complete Digital-to-analog Converter (DAC) with output amplifiers and Zener voltage reference 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 AD7237 has a double buffered interface structure and an 8-bit wide data bus with data loaded to the respective input latch in two write operations. An asynchronous LDAC signal on the AD7237A updates the DAC latches and analog outputs. A REF OUT/REF IN function is provided which allows either the on-chip 5V reference or an external reference to be used as a reference voltage for the part. The output amplifiers are capable of developing 10V across a 2kR load to GND. It is fabricated in linear compatible CMOS (LC²MOS), an advanced, mixed technology process that combines precision bipolar circuits with low power CMOS logic.
