The OP297GPZ is a low bias current precision dual Operational Amplifier utilizes a super-beta input stage with bias current cancellation to maintain picoamp bias currents at all temperatures. Its 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, 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 120dB. The OP297"s power supply rejection of over 120dB minimizes offset voltage changes experienced in battery powered systems. Supply current of the OP297 is under 625µA per amplifier and it can operate with supply voltages as low a ±2V. Input bias current of the OP297 is under 100pA at 25°C and is under 450pA over the military temperature range.
● 100pA Maximum very low bias current
● 2000V/mV Minimum very high open-loop gain
● 625µA Maximum low supply current (per amplifier)
