Simple Temperature Sensing IC

December 3, 2009 | Amateur Radio, electronics | By: Mark VandeWettering

A couple of projects that I’ve been pondering could make use of a little temperature sensing chip. Microchip makes this little gadget, the MCP9700A, which could be quite useful, and can be had for about $.35 from Digikey or Mouser. It comes in a simple TO-92 package, or smaller surface mount chips.
