资 源 简 介
The OP471 is a monolithic quad op amp featuring low noise,11 nV/÷Hz Max @ 1 kHz, excellent speed, 8 V/ms typical, again bandwidth of 6.5 MHz, and unity-gain stability.The OP471 has an input offset voltage under 0.8 mV and aninput offset voltage drift below 4 mV/∞C, guaranteed over the fullmilitary temperature range. Open-loop gain of the OP471 is over500,000 into a 10 kW load ensuring outstanding gain accuracyand linearity. The input bias current is under 25 nA limiTIngerrors due to signal source resistance. The OP471’s CMR ofover 105 dB and PSRR of under 5.6 mV/V significantly reduceerrors caused by ground noise and power supply fluctuaTIons.The OP471 offers excellent amplifier matching which is importantfor applicaTIons such as mulTIple gain blocks, low-noise instrumentationamplifiers, quad buffers and low-noise active filters.The OP471 conforms to the industry standard 14-lead DIPpinout. It is pin-compatible with the LM148/LM149, HA4741,RM4156, MC33074, TL084 and TL074 quad op amps and canbe used to upgrade systems using these devices.
