LM2917EP - (LM2907EP / 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
LM2917EP Features
* n Ground referenced tachometer input interfaces directly with variable reluctance magnetic pickups n Op amp/comparator has floating transistor output n 50 mA sink or source to operate relays, solenoids, meters, or LEDs n Frequency doubling for low ripple n Tachometer has built-in hysteresis with eit
