Locating two components

[gringo8217]

Hi

Simple question really , I am trying to simulate a driver circuit of which I need a ic the ULN2003 and a  thermistor , I have searched through the libraries but to no avail or I have missed them, can someone confirm they are in the libarys , I am using multisim 12 , and if so highlight the heading they are under !!

                                                                 Many Thanks

Hi Daz,

The ULN2003 is not in the database but this part looks like it's just an inverter and a diode so you can use the components in Multisim to create the internal circuit of the ULN2003.  We don't have a thermistor as well, but you can use a voltage control resistor (VCR) to emulate thermistor.  The input to the VCR is voltage but it represents temperature, and you can use any voltage sources (example ABM source) that let you to enter an expression to control the resistor.

How to use an ABM source

Thanks for the reply and explanation
