The OP-471
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.
The OP471 has an input offset voltage under 0.8 mV and an input offset voltage drift below 4 mV/guaran-teed over the full military temper-ature range. Open-loop gain of the OP471 is over 500,000 into a 10 kW load ensuring outstanding gain accuracy and linearity. The inputbias 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 an-d power supply fluctu-ations.
The OP471 offers excellent amplifier matching which is important for applications such as multiple gain blocks, low-noise instru- mentation a-mplifiers, quad buffers and low-noise active filters. The OP471 conforms to the industry st-andard 14-lead DIP pinout. It is pin-compatible w-ith the LM148/LM149, HA4741, RM4156, MC3-3074, TL084 and TL074 quad op amps and can be used to upgrade systems using these de-vices.
For applications requiring even lower voltage noise the OP470 with a voltage density of 5 nV/˜Hz Max @ 1kHz is rec-ommended.
