AD7376

APPLICATIONS INFORMATION

HIGH VOLTAGE DAC

PROGRAMMABLE POWER SUPPLY

The AD7376 can be configured as a high voltage DAC as high

as 30 V. The circuit is shown in Figure 32. The output is

With a boost regulator such as ADP1611, AD7376 can be used

as the variable resistor at the regulator’s FB pin to provide the

programmable power supply (see Figure 33). The output is
