Analog Devices AN-117 OP-42 SPICE Macro-Model Application Note
This document describes an advanced SPICE macro-model for the OP-42 high-speed, fast-settling precision operational amplifier. The model is designed to be compatible with PSpice and HSPICE simulation tools. It utilizes multiple frequency poles and zeroes to accurately simulate the AC and transient responses of the OP-42, accommodating 8 poles and 2 zeroes for sufficient simulation accuracy. The model relies on RC networks to produce these poles and zeroes, with stages separated by voltage-controlled current sources to prevent interaction between pole and zero locations.
