OP297FPZ

Instrumentation, Op Amps, Buffer Amps Overview

The OP297FPZ is a dual precision operational amplifier manufactured by Analog Devices Inc. in an 8-lead PDIP package. It features a maximum input offset voltage of 100 μV and a maximum drift of 2.0 μV/°C over the operating temperature range. The device operates on supply voltages from ±2 V to ±20 V with a typical gain bandwidth product of 500 kHz. Input bias current is specified at a maximum of 750 pA, while the supply current per amplifier is 750 μA maximum.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the OP297 handle input bias current compared to FET input op amps?

The OP297 uses a super-beta input stage with bias current cancellation, maintaining picoamp bias currents at all temperatures, whereas FET input op amps typically see bias currents double for every 10°C rise.

What is the common-mode rejection ratio specification?

The common-mode rejection ratio is specified as a minimum of 114 dB and a typical value of 130 dB under standard operating conditions.
