AD5337ARMZ

AD5337 is a dual channel, 8-bit buffered voltage output DAC. It operates from single 2.5V to 5.5V supply, consuming 250μA at 3V. The outputs of DAC can be updated simultaneously using the software LDAC function. The parts incorporate a power-on reset circuit to ensure that the DAC outputs power upto 0V and remain there until a valid write to the device takes place. The low power consumption of this part in normal operation makes it ideally suited to portable battery-operated equipment. It is widely used in application such as portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators, industrial process control etc.
