EL2245C, EL2445C

Dual/Quad Low-Power 100MHz Gain-of-2 Stable Op Amp

good AC performance, parasitic capacitances should be

kept to a minimum at both inputs and at the output.

Resistor values should be kept under 5k

Ω because of the

RC time constants associated with the parasitic capaci-

tance. Metal-film and carbon resistors are both

acceptable, use of wire-wound resistors is not recom-

mended because of their parasitic inductance. Similarly,

capacitors should be low-inductance for best

performance.

The EL2245C/EL2445C Macromodel

This macromodel has been developed to assist the user

in simulating the EL2245C/EL2445C 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

non-linearities

settling-time

temperature effects

CMRR

manufacturing variations

PSRR
