EL4094C

Video Gain Control Fader

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

r2 911 0 90

Input channel A

Signal path DC distortions

VGAIN I-V characteristics

VGAIN overdrive recovery delay

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 VG operating range

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
