good AC performance, parasitic capacitances should be
kept to a minimum at both inputs and at the output.
Resistor values should be kept under 5 k
the RC time constants associated with the parasitic
capacitance. Metal-film and carbon resistors are both
acceptable, use of wire-wound resistors is not recom-
mended because of their parasitic inductance. Similarly,

The EL2244C/EL2444C Macromodel
This macromodel has been developed to assist the user
in simulating the EL2244C/EL2444C with surrounding
circuitry. It has been developed for the PSPICE simula-
tor (copywritten by the Microsim Corporation), and may
need to be rearranged for other simulators. It approxi-
mates DC, AC, and transient response for resistive
loads, but does not accurately model capacitive loading.
This model is slightly more complicated than the models
used for low-frequency op-amps, but it is much more
accurate for AC analysis.
The model does not simulate these characteristics
accurately:
noise
settling-time
CMRR
PSRR
non-linearities
temperature effects
