I don't have any experience in hardware. I am writing a simple program in Raspberry pi to write audio samples to the DAC MCP4725. Next, I want to connect to the small speaker. What should be the rating of the speaker? I need a simple circuit to do so. Like, I checked that I need to connect the ouput of MCP4725 to a capacitor to get a pure AC signal. Next, I need to amplfiy this to drive a small speaker. I am planning to connect this to 3W minimum speaker 4 ohms or 8 ohms. What are the things I need to check in the datasheet of MCP4725 in order to drive the audio?
Here is the datasheet -
