OP249 SPICE MACRO-MODEL
Figures 53 and Table I show the node and net list for a SPICE
macromodel of the OP249 The model is a simplified version of
the actual device and simulates important dc parameters such as

SY
. AC parameters such as
slew rate, gain and phase response and CMR change with fre-
quency are also simulated by the model.

Figure 53. OP249 Macro-Model
The model uses typical parameters for the OP249. The poles
and zeros in the model were determined from the actual open
and closed-loop gain and phase response of the OP249. In this
way the model presents an accurate ac representation of the
actual device. The model assumes an ambient temperature of
25
°
C.
