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 k

W 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.
