Ca3046 Lm3046 Spice Model

[jackinnj]

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)

retype the whole thing in the PDF with a Notepad and save it as a require Spice file name.

uuuhhhh, isn't that what I just did for y'all?

An externally hosted image should be here but it was not working when we last tested it.

LM3046 is an interesting chip
several NPN in same IC

Perfect for my discrete Bandgap Voltage reference!!! 😎

• Two matched pairs of transistors VBE matched ±5 mV
Input offset current 2 µA max at IC = 1 mA
• Five general purpose monolithic transistors
• Operation from DC to 120 MHz
• Wide operating current range
• Low noise figure: 3.2 dB typ at 1 kHz

Thanks, I have this chip in a RF VCO - might be interesting to attempt a simulation

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