OP297G Product Details
The OP297G 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 OP297G useful in a wide variety of applications.
Precision performance of the OP297G includes very low offset, under 50µV, and low drift, below 0.6µV/°C.Open-loop gain exceeds 2000V/mV insuring high linearity in every application.Errors due to common-mode signals are eliminated by the OP297's common-mode rejection of over 120 dB.The OP297's power supply rejection of over 120dB minimizes offset voltage changes experienced in battery powered systems.Supply current of the OP297G is under 625µA per amplifier and it can operate with supply voltages as low a ±2V.
The OP297G 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 25°C, but double for every 10°C rise in temperature, to reach the nanoamp range above 85°C.Input bias current of the OP297G is under 100pA at 25°C and is under 450pA over the military temperature range.
Combining precision, low power and low bias current, the OP297G 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 OP97;for a quad, see the OP497.
