*----------------------------------------------------------------------- * OPA2822 Wideband, Unity Gain Stable, Current Feedback Op Amp with Disable * Created 12/07/01 RS * Modified 8/29/02 RS for new transistor model * Modified 9/30/02 RS adjusted response * * * NOTES: * 1- Uses a multiple pole-zero topology * 2- For better convergence during transient analysis set: * .OPTIONS ITL4=40 * 3- This macromodel predicts room temperature performance * (T = 27 deg C) for: DC, small-signal AC, noise, and * transient simulations * 4- This macromodel does not predict: distortion * (harmonic, intermod, diff. gain & phase, ...), * temperature effects, board parasitics, differences * between package styles, and process changes * 5- F function are .sub circuit for PSpice. If using in Regular spice * you should change to normal F statements * F_F(designator) Node1 Node 2 F(designator) (gain value). * Insert them in the main subcircuit. * * |---------------------------------------------------------------| * | This macro model is being supplied as an aid to | * | circuit designs.
