Breadboard-tool: oscillator module April 05, 2013, 11:44:24 pm I recently build a small module consisting of a LTC6990 voltage controlled oscillator. This chip can generate square waves ranging from 488Hz up to 2MHz, and is controlled by a voltage divider an a set resistor:For some more explanations see my blog entry for it. Its rather small, and needs only three pins to be put into a breadboard. I think it is a nice addition to my toolbox. It's not as accurate as my crystal-based generator (which still waits for a blog entry), but much smaller... Last Edit: January 01, 1970, 01:00:00 am by Guest
