Analog Devices AD5721R 12-Bit Multiple Range Voltage Output Digital-to-Analog Converters (DACs) are serial input, voltage output DACs that operate from single supply voltages of 4.75V-30V or dual supply voltages of -16.5V to 0V VSS and 4.75V-16.5V VDD. With its integrated output amplifier, reference buffer, the single-channel AD5721R DACs provide an easy-to-use, universal solution.
