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. Figure 1.
