Product Introduction
The OP297 is the first dual op amp to pack precision performance into the space saving, industry-standard 8-lead SOIC package. The combination of precision with low power and extremely low input bias current makes the dual OP297 useful in a wide variety of applications.
Precision performance of the OP297 includes very low offset (less than 50μV and low drift (less than 0.6μV/°C. Openloop gain exceeds 2000V/mV, ensuring high linearity in every application.
Errors due to common-mode signals are eliminated by the common-mode rejection of over 120 dB which minimizes offset voltage changes experienced in battery-powered systems. The supply current of the OP297 is under 625 μA.
The OP297 uses 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 at 25°C but double for every 10°C rise in temperature, to reach the nanoamp range above 85°C.
