The OP470 is a high-performance monolithic quad operational amplifier with exceptionally low voltage noise, 5nV/√Hz@1kHz maximum, offering comparable performance to ADI'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 2mV/°C, guaranteed over the full military temperature range. Open loop gain of the OP470 is over 1,000,000 into a 10 kW load ensuring excellent gain accuracy and linearity, even in high gain applications. Input bias current is under 25nA, which reduces errors due to signal source resistance. The OP470's CMR of over 110dB guarantees excellent common mode rejection ratio over the full military temperature range.
