E GENERAL DESCRIPTION
The OP271 is a unity-gain stable monolithic dual op amp
featuring excellent speed, 8.5 V/ms typical, and fast settling
T ^{time, 2 ms typical to 0. 01%. The OP271 has a gain bandwidth}
of 5 MHz with a high phase margin of 62∞.
Input offset voltage of the OP271 is under 200 mV with input
offset voltage drift below 2 mV/∞C, guaranteed over the full
E ^{military temperature range. Open-loop gain exceeds 400,000}
into a 10 kW load ensuring outstanding gain accuracy and
linearity. The input bias current is under 20 nA limiting
errors due to source resistance. The OP271’s outstanding
L _{CMR, over 106 dB, and low PSRR, under 5.6 mV/V, reduce}
errors caused by ground noise and power supply fluctuations.
In addition, the OP27l exhibits high CMR and PSRR over a
wide frequency range, further improving system accuracy.
