standard OP27. The OP470 features an input offset voltage below 0.4 mV, excellent for a quad op amp, and an offset drift under 2 mV/∞C, The OP470 offers excellent amplifier matching which is impor- guaranteed over the full military temperature range. Open loop tant for applications such as multiple gain blocks, low noise gain of the OP470 is over 1,000,000 into a 10 kW load ensuring instrumentation amplifiers, quad buffers, and low noise active excellent gain accuracy and linearity, even in high gain applica- filters. tions. Input bias current is under 25 nA, which reduces errors due to signal source resistance. The OP470’s CMR of over 110 The OP470 conforms to the industry standard 14-lead DIP dB and PSRR of less than 1.8 mV/V significantly reduce errors pinout. It is pin compatible with the LM148/149, HA4741, due to ground noise and power supply fluctuations.
