The OP497GSZ is a precision picoampere input current quad Operational Amplifier for use with photocurrent monitors. Its combination of exceptional precision with low power and extremely low input bias current makes the quad OP497 useful in a wide variety of applications. Precision performance of the OP497 includes very low offset (<50µV) and low drift (<0.5µV/°C). Open-loop gain exceeds 2000V/mV ensuring high linearity in every application. Errors due to common-mode signals are eliminated by its common-mode rejection of >120dB. The OP497 has a power supply rejection of >120dB which minimizes offset voltage changes experienced in battery-powered systems. The supply current of the OP497 is <625µA per amplifier and it can operate with supply voltages as low as ±2V. The OP497 uses a superbeta input stage with bias current cancellation to maintain picoamp bias currents at all temperatures.
