The OP297 Rev. G is a dual low bias current precision operational amplifier with low bias current, high open-loop gain and high common-mode rejection, which is widely used in strain gauge and bridge amplifiers, high stability thermocouple amplifiers, instrumentation amplifiers, photocurrent monitors, high gain linearity amplifiers, long-term integrators/filters, sample-and-hold amplifiers, peak detectors, logarithmic amplifiers and battery-powered systems.
