The OP471GSZ is a monolithic quad Operational Amplifier features low noise and unity-gain stability. The OP471 has an input offset voltage under 0.8mV and an input offset voltage drift below 4µV/°C. Open loop gain of the OP471 is over 500000 into a 10kR load insuring outstanding gain accuracy and linearity. The input bias current is under 25nA limiting errors due to signal source resistance. The OP471"s CMR of over 105dB and PSRR of under 5.6µV/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, quad buffers and low-noise active filters. 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.
