Simplified Schematic FEATURES Excellent Speed: 8 V/ s Typ Low Noise: 11 nV/ ÷Hz @ 1 kHz Max Unity-Gain Stable High Gain Bandwidth: 6.5 MHz Typ Low Input Offset Voltage: 0.8 mV Max Low Offset Voltage Drift: 4 V/ C Max High Gain: 500 V/mV Min Outstanding CMR: 105 dB Min Industry Standard Quad Pinouts GENERAL DESCRIPTION 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/∞C, guaranteed over the full military temperature range. Open-loop gain of the OP471 is over 500,000 into a 10 k W 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. For applications requiring even lower voltage noise the OP470 with a voltage density of 5 nV/ ÷Hz Max @ 1 kHz is recommended.
