Head over to Cyrustek (http://www.cyrustek.com.tw/product-1.htm) and have a look at their line of IC's. I was looking at them not to long ago for a project I have going. Most of them have pretty simple serial interfaces. "Smart-Tweezers" use one of these devices.
A question: What's a "precision Capacitor"? High-impedance amplifier that doesn't need silly values?
