APPLICATIONS INFORMATION
HIGH VOLTAGE DAC
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

PROGRAMMABLE POWER SUPPLY
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

Note that the AD7376’s VDD is derived from the output. Initially
L1 acts as a short, and VDD is one diode voltage drop below +5 V.
The output slowly establishes to the final value.
The AD7376 shutdown sleep-mode programming can be used
to program a desirable preset level at power-up.
