GENERAL DESCRIPTION
The OP271 is a unity-gain stable monolithic dual op amp
featuring excellent speed, 8.5 V/ms typical, and fast settling
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
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
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.
