OP470GP: Very Low Noise Quad Operational Amplifier PDIP-14封装
The OP-470 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 OP-470 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 OP-470 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 OP-470'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 OP-470 is half that of four OP-27s, a significant advantage for power conscious applications. The OP-470 is unity-gain stable with a gain-bandwidth product of 6MHz and a slew rate of 2V/µs.
The OP-470 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 OP-470 conforms to the industry standard 14-pin DIP pinout. It is pin compatible with the OP-11, 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 OP-471, with a slew rate of 8V/µs, is recommended.
