Input Gain Adjustments for the Inverting Mode
Figure 17 shows a suggested inverting gain adjustment circuit.
In this circuit, gain adjustment is made using a potentiometer
(RP) in the feedback loop. The adjustments are effective for all
gains in the 1 to 10 V/V range.

Note: RF and RIN should have matched temperature coefficient

Output Offset Adjustments
Figure 18 illustrates one method of adjusting the output offset
voltage. Since the AD215 exhibits a nominal output offset of
–35 mV, the circuit shown was chosen to yield an offset correc-
tion of 0 mV to +73 mV. This results in a total output offset
range of approximately –35 mV to +38 mV.

Output Gain Adjustments
Since the output amplifier stage of the AD215 is fixed at unity
gain, any adjustments can be made only in a subsequent stage.
USING ISOLATED POWER
Each AD215 provides an unregulated, isolated bipolar power
source of
±15 V dc @ ±10 mA, referred to the input common.
This source may be used to power various ancillary components
such as signal conditioning and/or adjustment circuitry, refer-
ences, op amps or remote transducers. Figure 19 shows typical
connections.

CAUTION
The AD215 design does not provide short-circuit protection of
its isolated power supply. A current limiting resistor should be
placed in series with the supply terminals and the load in order
to protect against inadvertent shorts.
