Precision Picoampere Input Current Quad Operational Amplifier

The OP-497 is a quad op amp with precision performance in the space saving, industry standard 16-pin SOIC package. Its combination of exceptional precision with low power and extremely low input bias current makes the quad OP-497 useful in a wide variety of applications.
Precision performance of the OP-497 includes very low offset, under 50 V, and low drift, below 0.5 V/C. Open-loop gain exceeds 2000 V/mV insuring high linearity in every application. Errors due to common-mode signals are eliminated by the OP-497's common-mode rejection of over 120dB. The Op-497's power supply rejection of over 120dB minimizes offset voltage changes experienced in battery powered systems. Supply current of the OP-497 is under 625 A per Amplifier and it CAN operate with supply voltages as low as 2 V.
The OP-497 utilizes a superbeta input stage with bias current cancellation to maintain picoamp bias currents at all temperatures. This is in contrast to JFET input op amps whose bias currents start in the picoamp range at 25C, but double for every 10C rise in temperature, to reach th nanoamp range above 85C. Input bias current of the OP-497 is under 100 pA at 25C and is under 450 pA over the military temperature range.
Combining precision, low power and low bias current, the OP-497 is ideal for a number of applications including Instrumentation Amplifiers log Amplifiers photo-diode preamplifiers and long term integrators. For a single devide see the OP-97, for a dual see the OP-297.
