Video Instrumentation Amplifiers
Macromodel
This is a Pspice-compatible macromodel of the EL4430 video instrumentation
amplifier assembled as a subcircuit The pins are numbered sequentially
as the subcircuit interface nodes T1 is a transmission line which provides
a good emulation of the more complicated real device This model correctly
displays the characteristics of input clipping frequency response CMRR
both AC and DC output clipping output sensitivity to capacitive loads
gain accuracy slewrate limiting input bias current and impedance The
macromodel does not exhibit proper results with respect to supply current
supply sensitivities offsets output current limit differential gain or
phase nor temperature
