The OP470 is a high-performance monolithic quad operational amplifier with exceptionally low voltage noise, 5nV/(root)Hz at 1kHz Max, offering comparable performance to PMI's industry standard OP27. The OP470 features an input offset voltage below 0.4mV, excellent for a quad op amp, and an offset drift under 2µV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP470 is over 1,000,000 into a 10k Ohm load insuring excellent gain accuracy and linearity, even in high-gain applications. Input bias is under 25nA which reduces errors due to signal source resistance. The OP470's CMR of over 110dB and PSRR of less than 1.8µV/V significantly reduce errors due to ground noise and power supply fluctuations. Power consumption of the quad OP470 is half that of four OP27s, a significant advantage for power conscious applications. The OP470 is unity-gain stable with a gain-bandwidth product of 6MHz and a slew rate of 2V/µs. The OP470 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 OP470 conforms to the industry standard 14-pin DIP pinout. It is pin compatible with the OP11, LM 148/149, HA4741, HA5104, and RM4156 quad op amps and can be used to upgrade systems using these devices. For higher speed applications the OP471, with a slew rate of 8V/µs, is recommended. * Very Low-Noise, 5 nV/√Hz @ 1 kHz Max * Excellent Input Offset Voltage, 0.4 mV Max * Low Offset Voltage Drift, 2 µV/°C Max * Very High Gain, 1000 V/mV Min * Outstanding CMR, 110 dB Min * Slew Rate, 2 V/µs Typ * Gain-Bandwidth Product, 6 MHz Typ * Industry Standard Quad Pinouts * Available in Die Form https://elecena.pl/product/5067103/low-noise-quad-op-amp 2015-03-28 https://elecena.pl/product/5067103/low-noise-quad-op-amp 2018-03-29 https://elecena.pl/product/5067103/low-noise-quad-op-amp 2025-01-21
