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 The OP470 conforms to the industry standard 14-lead DIP due to signal source resistance. The OP470s CMR of over 110 pinout. It is pin compatible with the LM148/149, HA4741, dB and PSRR of less than 1.8 mV/V significantly reduce errors HA5104, and RM4156 quad op amps and can be used to up- due to ground noise and power supply fluctuations. Power grade systems using these devices. consumption of the quad OP470 is half that of four OP27s, a significant advantage for power conscious applications. The For higher speed applications, the OP471, with a slew rate of 8 OP470 is unity-gain stable with a gain bandwidth product of V/ms, is recommended. 6 MHz and a slew rate of 2 V/ms.
