EL4430,EL4431 Macromodel
*Macromodel
*This is a Pspice-compatible macromodel of the EL4430 video instrumentation amplifier assembled
*as a sub circuit. 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.
*Connections:
