Does it come with a datasheet, so you know how to wire it up?

It does not; but, easy enough to find with Google; search for mcp4131 datasheet

Is this compatible with an Arduino microcontroller?

Yes, make sure you read data sheet to wire correctly.

I am not the seller, but it's probably MCP4131-103E/Phttp://www.mouser.com/ProductDetail/Microchip-Technology/MCP4131-103E-P/?qs=hH%252bOa0VZEiAx39DWvGy4dg%3D%3D

It does its job

The media could not be loaded. It definitely works! This is just a simple sweep up-down on an LED. The program isn't weighted, it should be linear, but it doesn't quite look it. The weighting was not specified on this page, and it was not clearly stated on the datasheet (I'm not good at reading those yet so maybe it was) so keep that in mind.

These are re purchased from American company & resold for big markup.

Get these state-side, American made chips should not be purchased from China, yes?
