OP271: High Speed, Dual Operational Amplifier
The OP-271 is a unity-gain stable monolithic dual op amp featuring excellent speed, 8.5V/µs typical, and fast setting time, 2µs typical to 0.01%. The OP-271 has a gain bandwidth of 5MHz with a high phase margin of 62°.
Input offset voltage of the OP-271 is under 200µV with input offset voltage drift below 2µV/°C, guaranteed over the full military temperature range. Open-loop gain exceeds 400,000 into a 10k Ohm load ensuring outstanding gain accuracy and linearity. The input bias current is under 20nA limiting errors due to source resistance. The OP-271's outstanding CMR, over 106dB, and low PSRR, supply fluctuations. In addition, the OP-271 exhibits high CMR and PSRR over a wide frequency range, further improving system accuracy.
The OP-271 offers outstanding DC and AC matching between channels. This is especially valuable for applications such as multiple gain blocks, high-speed instrumentation and amplifiers, buffers and active filters.
The OP-271 conforms to the industry standard 8-pin dual op amp pinout. It is pin compatible with the TL072, TL 082, LF412, and 1458/1558 dual op amps and can be used to significantly improve systems using these devices.
