Default Ca3046 Lm3046 Spice Model

Intersil had this CA3046 model on their website -- it was in a PDF so had to be transcribed by hand -- there are other models for the transistor arrays on the Intersil site but the CA3046 seems to be most commonly used:

.model QCA3046 NPN (IS=10e-15 BF=145.7E00 XTI=3E00 VAR=1.00E2 IKF=46.7E-03
+EG=1.110E00 VAF=1.00e02 ISE=114.286E-15 NE=1.48E00 XTB=0
+BR=0.1 ISC=10.005e-15 NC=2 IKR=10e-3 RC=10 CSJC=991.71e-15
+MJC=.333 VJC=.75 FC=5.00e-01 CJE=1.02e-12 MJE=.336 VJE=.75
+TR=10e-9 TF=277.01e-12 ITF=1.75 XTF=309.38 VTF=16.37)

LM3046 is an interesting chip
several NPN in same IC

Perfect for my discrete Bandgap Voltage reference!!!

You can find this model at the LTspice support group:
http://tech.groups.yahoo.com/group/L.../files/%20Lib/
(you might need to register)
It is the CA3000 zip, towards the end of the list.
