How to generate a DC level on STM32F4 DAC?

I am using pin PA4 as a DAC output on an STM32F405. I then have a unity gain op-amp buffer. My supply is 3.3V.
What I want to do is rather than create a SINE output at some frequency, is to generate a DC signal. For example, at 2048 (ADC/2) I want a DC level of 1.65.
Basically, a DC level that is 3.3/4096.

Can someone please provide a sample DAC setup that would guide me on this, or some hints?
