APPLICATIONS INFORMATION
HIGH VOLTAGE DAC
The AD5292 can be configured as a high voltage DAC, with
output voltage as high as 33 V. The circuit is shown in Figure 70.

BOOSTED OUTPUT
For applications that require high current adjustments such as a
laser diode or tunable laser, a boosted voltage source can be
considered; see Figure 71.

Figure 71. Programmable Boosted Voltage Source
In this circuit, the inverting input of the op amp forces VOUT to
be equal to the wiper voltage set by the digital potentiometer.
The load current is then delivered by the supply via the N-channel
FET (U3). The N-Channel FET power handling must be adequate
to dissipate (VIN VOUT) × IL power. This circuit can source a
maximum of 100 mA with a 33 V supply.
HIGH ACCURACY DAC
It is possible to configure the AD5292 as a high accuracy DAC
by optimizing the resolution of the device over a specific
reduced voltage range. This is achieved by placing external
resistors on either side of the RDAC, as shown in Figure 72.
The improved ±1% R-Tolerance specification greatly reduces
error associated with matching to discrete resistors.

VARIABLE GAIN INSTRUMENTATION AMPLIFIER
The AD8221 in conjunction with the AD5291 and AD5292 and
the ADG1207, as shown in Figure 73, make an excellent
instrumentation amplifier for use in data acquisition systems.
The data acquisition system’s low distortion and low noise
enable it to condition signals in front of a variety of ADCs.
