componants in green colour means what?

[Anu13]

i want to use IC DAC8541 in my circuit, but it not working.

is there any meaning for componants in green colour?

Hi Anu13,

A green color component means that it is a layout only component. What that means is that there is no simulation model for that component but the footprint is available to allow you to design your PCB. Unfortunately, you will not be able to simulate this component.

Anu13,

You may be able to use the "VDAC16" which has a 16 bit parallel interface.   Although it won't function exactly like the

DAC8541, it might give you the approximate behavior.  Also if you are familiar with SPICE or would like a challenge, you can try to reuse and modify the VDAC16 model (create a custom part with the Component Wizard and copy the VDAC16 model into the part and then edit to support any additional functionality).

hello sir,

i want to use 16 bit DAC, then only VDAC16 & IDAC16 is available.

but while building hardware for the same circuit which DAC i should use?

Bcoz VDAC & IDAC are not available in market.
