AD7247ABRZ

AD7247A is a dual channel, voltage output digital-to-analog 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 accepts 12-bit parallel data which is loaded into the respective DAC latch using the WR input and a separate Chip Select input for each DAC. An asynchronous LDAC signal on the converter 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. 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.
