Simulation mit Fehlern

Hallo,

wenn ich diese importierten Modelle unter LTspice laufen lasse hab ich Probleme:


*LF412 LOW OFFSET, LOW DRIFT DUAL JFET INPUT OP-AMP MODEL
*
* connections: non-inverting input
* | inverting input
* | | positive power supply
* | | | negative power supply
* | | | | output
* | | | | |
* | | | | |
.SUBCKT LF412 1 2 99 50 28
*
*Features:
*Fast settling time (.01%) = 2uS
*High bandwidth = 3MHz
*High slew rate = 10V/uS
*Low offset voltage = 1mV
*Low supply current = 1.8mA
*NOTE: Model is for single device only and simulated
* supply current is 1/2 of total device current.

Beim LF412 klappt Frequenzgang und Klirranalyse, Rauschen ist dubios.
Beim AD412 stimmen Frequenzgang und Rauschen, bei der Transientenanalyse mit 1k Sinus
hängt sich Spice nach der ersten Halbwelle auf.
Stimmen die Modelle nicht oder passen sie einfach nicht zu LT?
