The AD627 is a true instrumentation amplifier built using two feedback loops. Its general properties are similar to those of the classic 2-op amp instrumentation amplifier configuration, and can be regarded as such, but internally the details are somewhat different. The AD627 uses a modified current feedback scheme which, coupled with interstage feedforward frequency compensation, results in a much better CMRR (common-mode rejection ratio) at frequencies above dc (notably the line frequency of 50 Hz to 60 Hz) than might otherwise be expected of a low power instrumentation amplifier.

However, some chip resistors can have TCs of 200 ppm/ C or even 250 ppm/ C. Even when a 1% 100 ppm/C resistor is used, the gain accuracy of the in-amp will be degraded. 01% (100 ppm/C) for every C change in temperature. The initial gain error can easily be subtracted out in software, but to correct for the error vs. temperature, frequent recalibrations (and a temperature sensor) would be required. 1%) accuracy for a 10C change.

When the bridge is balanced, the differential input voltage at A1, and thus its output, will be zero.
