GAIN SELECTION
The AD622 gain is resistor programmed by RG or, more
precisely, by whatever impedance appears between Pin 1 and
Pin 8. The AD622 is designed to offer gains as close as possible
to popular integer values using standard 1% resistors. Table 6
shows required values of RG for various gains. Note that for
G = 1, the RG pins are unconnected (RG = ∞). For any arbitrary
gain, RG can be calculated by using the formula

To minimize gain error, avoid high parasitic resistance in series
with RG. To minimize gain drift, RG should have a low temperature
coefficient less than 10 ppm/°C for the best performance.

INPUT AND OUTPUT OFFSET VOLTAGE
The low errors of the AD622 are attributable to two sources:
input and output errors. The output error is divided by G when
referred to the input. In practice, the input errors dominate at
high gains and the output errors dominate at low gains. The
total VOS for a given gain is calculated as follows:
Total Error RTI = input error + (output error/G)
Total Error RTO = (input error × G) + output error
REFERENCE TERMINAL
The reference terminal potential defines the zero output voltage
and is especially useful when the load does not share a precise
ground with the rest of the system. The reference terminal provides
a direct means of injecting a precise offset to the output, with an
allowable range of 2 V within the supply voltages. Parasitic
resistance should be kept to a minimum for optimum CMR.
INPUT PROTECTION
The AD622 safely withstands an input current of ±60 mA for
several hours at room temperature. This is true for all gains and
power on and off, which is useful if the signal source and amplifier
are powered separately. For longer time periods, the input
current should not exceed 6 mA.
For input voltages beyond the supplies, a protection resistor should
be placed in series with each input to limit the current to 6 mA.
These can be the same resistors as those used in the RFI filter.
High values of resistance can impact the noise and AC CMRR
performance of the system. Low leakage diodes (such as the
BAV199) can be placed at the inputs to reduce the required
protection resistance.
