This circuit uses two kinds of transistor, the 2N2219 bipolar and the 2N3069 JFET. Both of them are used as voltage devices between the current sensing resistor and the output. As the … Continue reading →]]> http://www.simplecircuitdiagram.com/2010/03/06/precision-current-source/feed/ 0 http://www.simplecircuitdiagram.com/2009/12/25/linear-tec-thermo-electric-cooler-driver/ http://www.simplecircuitdiagram.com/2009/12/25/linear-tec-thermo-electric-cooler-driver/#comments Fri, 25 Dec 2009 05:55:53 +0000 Adam http://www.simplecircuitdiagram.com/?p=332 TEC is one of the cooler that was popular because of its robustness and maintenance free characteristic. This article shows one example of the TEC driver. To operate this circuit operates we need a single +5V supply and drives the … Continue reading →]]> http://www.simplecircuitdiagram.com/2009/12/25/linear-tec-thermo-electric-cooler-driver/feed/ 0
