The OP497 from Analog Devices is a quad operational amplifier designed for precision applications. It offers exceptional performance characteristics such as a very low input bias current, reaching 150 pA maximum at 25°C and 300 pA maximum over the -40°C to +85°C range. The device also features a low offset voltage of 75 μV maximum and a low offset voltage drift of 1.0 μV/°C maximum.
With a very high open-loop gain of 2000 V/mV minimum, the OP497 ensures high linearity. It boasts a high common-mode rejection ratio of 114 dB minimum and a power supply rejection ratio of over 120 dB, minimizing errors from common-mode signals and supply variations. The quad op amp operates from supply voltages ranging from ±2 V to ±20 V and consumes a low supply current of 625 μA maximum per amplifier.
Applications for the OP497 include strain gage and bridge amplifiers, high stability thermocouple amplifiers, instrumentation amplifiers, and photocurrent monitors. Its precision performance and low power consumption make it suitable for battery-powered systems and long-term integrators/filters.
