Gain from 1 to 10000 set by a single external resistor: G = (49.4 kOhm \/ RG) + 1. 50uV max input offset and 100 dB CMRR at G=10 provide excellent DC accuracy for bridge and sensor measurements. 1nA input bias current minimizes error with high-impedance sensors.","working_principle":"Three-op-amp instrumentation amplifier topology. Two input buffer amplifiers provide high input impedance and differential gain. A subtractor stage removes common-mode voltage. The single gain resistor RG sets the differential gain without affecting CMRR. The laser-trimmed thin-film resistors ensure high CMRR and low offset without external trimming.","pin_description":"
