General Description
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 low ripple, full input protection in two versions (LM2907-8EP, LM2917-8EP) and its output swings to ground for a zero frequency input.

Features
■ Ground referenced tachometer input interfaces directly with variable reluctance magnetic pickups
■ Op amp/comparator has floating transistor output
■ 50 mA sink or source to operate relays, solenoids, meters, or LEDs
■ Frequency doubling for low ripple
■ Tachometer has built-in hysteresis with either differential input or ground referenced input
■ Built-in zener on LM2917EP
■ ±0.3% linearity typical
■ Ground referenced tachometer is fully protected from damage due to swings above VCC and below ground

Applications
■ Selected Military Applications
■ Selected Avionics Applications
