Aerospace Very Low-Noise Quad Op Amp
The OP470 features an input offset voltage below 0.4mV, excellent for a quad op amp, 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 reisitance. 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 typical.
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 and LM 148 quad op amps and can be used to upgrade systems using these devices.
