A precision instrumentation amplifier: it amplifies the difference between two inputs while rejecting the noise both share. Gain is set by a single external resistor, G = 1 + 49.4 kOhm / RG, anywhere from 1 to 1000, on supplies from plus/minus 2.3 V to plus/minus 18 V and only 1.3 mA of current. With 9 nV per root Hz of input noise it is the standard front end for load cells, strain gauges, thermocouples and ECG circuits.
Key features
- Gain 1 to 1000 set by one external resistor
