OP471: High Speed, Low Noise Quad Operational Amplifier
The OP-471 is a monolithic quad op amp featuring low-noise, 11nV/(root)Hz Max at 1kHz, excellent speed, 8V/us typical, a gain-bandwidth of 6.5MHz, and unity-gain stability.
The OP-471 has an input offset voltage under 0.8mV and an input offset voltage drift below 4uV/°C. guaranteed over the full military temperature range. Open loop gain of the OP-471 is over 500,000 into a 10k Ohm load insuring outstanding gain accuracy and linearity. The input bias current is under 25nA limiting errors due to signal source resistance. The OP-471's CMR of over 105dB and PSRR of under 5.6uV/V significantly reduce errors caused by ground noise and power supply fluctuations.
The OP-471 offers excellent amplifier matching which is important for applications such as multiple gain blocks, low-noise instrumentation amplifiers, quad buffers and low-noise active filters.
The OP-471 conforms to the industry standard 14-pin DIP pinout. It is pin compatible with the OP-11, LM 148/149, HA4741, 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 OP-470, with a voltage density of 5nV/(root)Hz Max at 1kHz, is recommended.
