APPLICATIONS
Process controls Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators
ence buffer is provided on chip. The AD5025/AD5045/AD5065 incorporate a power-on reset circuit that ensures the DAC output powers up zero scale or midscale and remains there until a valid write takes place to the device. The AD5025/AD5045/AD5065 contain a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in power-down mode. The parts are put into power-down mode over the serial interface. Total unadjusted error for the parts is
