Figure 45. Use of Reference Terminal to Provide Output Offset
Figure 46. Voltage-to-Current Converter
An instrumentation amplifier can be turned into a voltage-
to-current converter by taking advantage of the sense and
reference terminals, as shown in Figure 46.
By establishing a reference at the low side of a current setting
resistor, an output current may be defined as a function of input
voltage, gain, and the value of that resistor. Because only a small
current is demanded at the input of the buffer amplifier (A2)
the forced current, IL, largely flows through the load. Offset and
drift specifications of A2 must be added to the output offset and
drift specifications of the AD524.
