The OP471 has an input offset voltage under 0.8 mV and an 16-Lead SOIC input offset voltage drift below 4 mV/C, guaranteed over the full (S-Suffix) military temperature range. Open-loop gain of the OP471 is over 500,000 into a 10 kW load ensuring outstanding gain accuracy 1 16 OUT A OUT D and linearity. The input bias current is under 25 nA limiting 2 15 IN A IN D errors due to signal source resistance. The OP471s CMR of 3 14 over 105 dB and PSRR of under 5.6 mV/V significantly reduce +IN A +IN D errors caused by ground noise and power supply fluctuations.

NC 8 9 NC The OP471 conforms to the industry standard 14-lead DIP pinout. It is pin-compatible with the LM148/LM149, HA4741, NC = NO CONNECT RM4156, MC33074, TL084 and TL074 quad op amps and can be used to upgrade systems using these devices. For applications requiring even lower voltage noise the OP470 with a voltage density of 5 nV/Hz Max 1 kHz is recommended. V+ BIAS OUT IN +IN V Figure 1. Simplified Schematic REV.
