7.2.2 DAC Output Gain and Buffer

Many applications require precise control of a high voltage signal, but existing digital-to-analog converters (DACs) have a limited output range of 0V to 5V. The OPAx591 is designed for use as an output driver stage with gain to provide a high voltage, bipolar output voltage. The OPAx591 offers excellent dc precision at high voltage, small form factor packages, and low power consumption, making these amplifiers a great choice for high-channel, high density systems common in many test and measurement applications.
