Can someone please provide a proteus module for DAC ??

[Tina10]

Can someone be kind enough to provide me a proteus module to operate a DAC. I read few posts and it seems it is not an easy task for someone like me to make one easily as I don't know too much about electronics. All I need is a uC connected to a DAC. I would like to have serial window in which I type the 10 bit number and the DAC outputs the corresponding voltage.

I am sure everyone can use this kind of modular attachment in their proteus designs and check their simulations properly.

Anyone, Please help?
I am only asking this because I find it impossible to provide voltage to my ADC in 1.22mV increments.

What real life parts are you having trouble with? What exactly are you trying to do?

Hi mackrackit, I have developed a circuit in proteus to learn more about ADC which I am trying to simulate. It's just for learning currently what I am doing. I tried using the POT component, but the increments cannot be controlled precisely. I saw Darrel advising in some post to use DAC in the library, but that's way out of my league currently. So I was wondering if someone would be kind enough to create a module in proteus which I can add to my design and connect the output of the created module to my simulation, that way I can have full control over ADC 10 bit range. Having a micro controlling the ADC will be a big benefit as using a mirco and Virtual terminal, any value can just be written in the Virtual terminal (0-4096) as an input to the micro and the micro can make the ADC output the corresponding voltage.

If Darrel does not see this thread you might try contacting him directly.

I do not use SIMs, that is why I ask about the real life parts. Do you have a bread-board?

Hi,

I dont use sims either but why dont you connect a signal generator and feed the signal to an

--R --- R ---
C C
GND

low pass filter and after that you should have a DC level that adjusted by the amplitude from the signal generator. If you use PWM signal it should be linear.
