The OP471 has an input offset voltage under 0.8 mV and an input offset voltage drift below 4 mV/∞C, guaranteed over the full military temperature range. Open-loop gain of the OP471 is over 500,000 into a 10 kW load ensuring outstanding gain accuracy and linearity. The input bias current is under 25 nA limiting errors due to signal source resistance. The OP471’s CMR of over 105 dB and PSRR of under 5.6 mV/V significantly reduce errors caused by ground noise and power supply fluctuations. The OP471 offers excellent amplifier matching which is important for applications such as multiple gain blocks, low-noise instrumentation amplifiers, q...
