Dual Low Bias Current Precision Operational Amplifier

The OP-297 is the first dual op amp to pack precision performance into the space-saving, industry standard 8-pin SO package. Its combination of precision with low power and extremely low input bias current makes the dual OP-297 useful in a wide variety of applications.
Precision performance of the OP-297 includes very low offset, under 50V, and low drift, below 0.6V/C. Open-loop gain exceeds 2000V/mV insuring high linearity in every application. Errors due to common-mode signals are eliminated by the OP-297's common-mode rejection of over 120 dB. The OP-297's power supply rejection of over 120dB minimizes offset voltage changes experienced in battery powered systems. Supply current of the OP-297 is under 625A per Amplifier and it CAN operate with supply voltages as low a 2V.
The OP-297 utilizes a super-beta input stage with bias current cancellation to maintain picoamp bias currents at all temperatures. This is in contrast to FET input op amps whose bias currents start in the picoamp range of 25C, but double for every 10C rise in temperature, to reach the nanoamp range above 85C. Input bias current of the OP-297 is under 100pA at 25C and is under 450pA over the military temperature range.
Combining precision, low power and low bias current, the OP-297 is ideal for a number of applications including Instrumentation Amplifiers log Amplifiers phot-diode preamplifiers and long-term integrators. For a single device, see the OP-97; for a quad, see the OP-497.
