AD7237AARZ

AD7237A is a dual channel, voltage output digital-to-analogue converter port. It has output amplifier and zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. It 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 converter updates the DAC latches and analogue outputs. It is fabricated in linear compatible CMOS (LC²MOS), an advanced, mixed technology process that combines precision bipolar circuits with low power CMOS logic. A REF OUT/REF IN function is provided which allows either on-chip 5V reference or an external reference to be used as a reference voltage for the part.
