Analog Devices OP497 Manuals

The document introduces the features and performance of the Precision Picoampere Input Current Quad Operational Amplifier OP497 Rev. E. The features include low offset voltage, low offset voltage drift, very low bias current, very high open-loop gain, low supply current, and high common-mode rejection. It is suitable for applications such as strain gage 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 OP497 is a quad op amp with precision performance in the space-saving, industry standard 16-lead SOlC package. Its com- bination of exceptional precision with low power and extremely low input bias current makes the quad OP497 useful in a wide variety of applications.
