I use 8bit DAC in my circuit,it behaves very strange.I can receive same voltage lever for different combinations like:

0->0V

1->39.062mV

2->39.062mV

3->78.125mV

4->78.125mV

5->117.187mV

6->117.187mV

The right Resolution of this device is very important for my class project.

I attached the circuit..

Thanks for your help.

Hi Sergei,

This is known issue in Multisim 10.0. It was fixed in Multisim 10.1. We apologize for this mistake. You have a few options:

• Upgrade your Multisim (Multisim 11.0 is available as a free trial download here)
• Use a the 8 MSB of a 16 bit DAC and ground the 8 LSB

Hope that helped.
