AD7237JRZ

AD7237 is a dual 12bit complete DAC with double buffered byte loading. It is microprocessor compatible, with high speed data latches and interface logic. This accepts 12bit parallel data which is loaded into the respective DAC latch using the WR input and a separate chip select input for each DAC. This 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 this updates the DAC latches and analog outputs. It is fabricated in linear compatible CMOS (LC²MOS), an advanced, mixed technology process that combines precision bipolar circuits with low power CMOS logic.
