Well, sort of.
There are details you have not shared.
Frequency and max voltage required at the (+) input,
The Analogwrite() is really a PWM signal.
That signal goes from 0V to 5V as a string of pulses.
Filtering can help smooth out those pulses.
Professor Google can help you with that filter.
Good Luck
But in fact, no!
