–IN C  
The OP471 is a monolithic quad op amp featuring low noise,  
11 nV/÷Hz Max @ 1 kHz, excellent speed, 8 V/ms typical, a  
gain bandwidth of 6.5 MHz, and unity-gain stability.

OUT C  
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 instru-  
mentation amplifiers, quad buffers and low-noise active filters.

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