OP297 SMD IC Price in Pakistan

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 incudes very low offset(less than 50 μV) and low drift (less than 0.6 μV/°C). Open-loop gain exceeds 2000 V/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.

Moreover, the OP297 utilizes a super-beta input stage with bias current cancellation to sustain picoamp bias currents across all temperatures. Unlike FET input op amps, whose bias currents initiate in the picoamp range at 25°C but double with every 10°C increase in temperature, reaching the nanoamp range above 85°C. The input bias current of the OP297 remains under 100 pA at 25°C and under 450 pA over the military temperature range per amplifier. Furthermore, this component can function with supply voltages as low as ±2V.

The OP297, with its precision, low power, and low bias current, is ideal for various applications such as instrumentation amplifiers, log amplifiers, photodiode preamplifiers, and long-term integrators.
