hi,,,

In pic18f4550 can we analog output????

 

The same as with any micro with output pins.

 

Basically no, but they can do PWM or you could connect an external DAC.

 

How "analog" do you want your output? What is the end result you want to achieve?

You can use pwm to switch pretty quickly to 'simulate' analog, but then again, if you are trying to send a signal to .50 cent analog component that could be replaced with a .50 cent digital one, it may not be worth the trouble.

What do you want to do?

 

This worked for me:

As they said in the previous posts, it all depends on what your doing.
