EL4094C Macromodel
This macromodel is offered to allow simulation of
general EL4094 behavior We have included
these characteristics
Small-signal frequency response
Output loading effects
Input impedance
Off-channel feedthrough
Output impedance over frequency
Signal path DC distortions
V
V
100% gain error
These will give a good range of results for various
operating conditions but the macromodel does
not behave identically as the circuit in these ar-
eas
Temperature effects
Signal overload effects
Signal and V
Current-limit
Video and high-frequency distortions
Supply voltage effects
Slewrate limitations
Noise
Power supply interactions
The macromodel’s netlist is based on the Pspice
simulator (copywritten by the Microsim Compa-
ny) Other simulators may not support the
POLY function which is used to implement mul-
tiplication as well as square-low nonlinearities
