LM2917EP - Enhanced Plastic Frequency to Voltage Converter

The LM2907EP, LP2917EP series are monolithic frequency to voltage converters with a high gain op amp/comparator designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate. The tachometer uses a charge pump technique and offers frequency doubling for .
