Normal Operation Theory

OPA860IDG4 is a high-performance precision operational amplifier designed for a variety of linear and instrumentation applications. It operates in a differential configuration with a single-ended output, and utilizes a single supply voltage. This amplifier features high input impedance and low supply current, with good power supply rejection ratio. Its input overload conditions are internally protected and never need to be reset.

Although OPA860IDG4 is a single-ended amplifier, it operates in a differential configuration. The input terminals of the amplifier are reversibly shorted internally, so that the differential input is zero. The differential input voltage is then amplified by a gain that is set by the external gain element. The output is taken from the inverting input terminal and is connected to a load through an external amplifier. The output is inversely proportional to the differential input voltage.
