Hey all,

Although its been a few years since I've been active in FIRST I find myself coming back to ChiefDelphi whenever I have a particularly unique tech question that doesn't come up in Google. I like it, its like "I got people" but for robots....

Anyways,

I need to create an EM field generator for a project that I'm working on. It needs to be small (say 3"x3x3 container) and give 1mA current to a coil at a specific frequency with a sine wave.

Whats the best solution for this? Is there a small IC that I can use, maybe configure with a few resistors to get my specified frequency and let it go? Or am I going to have to pull some software magic with a DAC?

Let me know what you guys think, or if you need more info.

I appreciate it!
