OP471GS

高速，低噪声四路运算放大器 High Speed, Low Noise Quad Operational Amplifier

Product Details

The OP471 is a monolithic quad op amp featuring low-noise, 11nV/rootHz Max at 1kHz, excellent speed, 8V/µs typical, a gain-bandwidth of 6.5MHz, and unity-gain stability.

The OP471 has an input offset voltage under 0.8mV and an input offset voltage drift below 4µV/°C. guaranteed over the full military temperature range. Open loop gain of the OP471 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 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.

The OP471 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 OP470, with a voltage density of 5nV/rootHz Max at 1kHz, is recommended.
