OP497 SPICE MACRO-MODEL
Figure 12 and Table I show the node and net list for a SPICE
macro-model of the OP497. The model is a simplified version of
the actual device and simulates important dc parameters such as
V
OS
, I
OS
, I
B
, A
VO
, CMR, V
O
, and I
SY
. AC parameters such as slew
rate, gain and phase response, and CMR change with frequency
are also simulated by the model.
The model uses typical parameters for the OP497. The poles and
zeros in the model were determined from the actual open and
closed-loop gain and phase response of the OP497. In this way,
the model presents an accurate ac representation of the actual
device. The model assumes an ambient temperature of 25
°
C.
