Analog Devices AN-132 OP-470 SPICE Macro-Model Application Note
This document describes a SPICE macro-model for the OP-470 very low noise quad operational amplifier. The model was tested with and is compatible with PSpice and HSpice. It includes the schematic and net-list necessary for simulation.
The macro-model represents one of the four amplifiers on one chip and uses RC networks to produce multiple poles for accurate AC and transient responses. It accommodates six poles and two zeros to accurately model the OP-470. The model is designed to be simple, using almost entirely ideal, linear circuit elements to reduce simulation time.
