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.
The OP297 is a dual operational amplifier designed to pack precision performance into a space-saving 8-lead SOIC package. It features very low offset voltage (50 μV maximum), low offset voltage drift (0.6 μV/°C maximum), and extremely low input bias current (100 pA maximum). The device operates from supply voltages as low as ±2 V up to ±20 V and is ideal for battery-powered systems and high-precision applications.
