| This instrumentation amplifier module has two independent instrumentation amplifier sections. The instrumentation amplifier with an internal high precision feedback network. It is used as a difference amplifier, so that it amplifies the difference between two ground reference input signals. The instrumentation amplifier has common mode rejection ratio (CMRR) or its ability to reject ground reference in phase signals common to both inputs such as main's frequency hum, even though the two input signal sources may be unbalanced by as much as 1 Ohm. |
