LM2907EP - (LM2907EP / LM2917EP) Enhanced Plastic Frequency to Voltage Converter

Download the LM2907EP datasheet PDF. This datasheet also covers the LM2917EP variant, as both devices belong to the same (lm2907ep / lm2917ep) enhanced plastic frequency to voltage converter family and are provided as variant models within a single manufacturer datasheet.

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.

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 either differential input or ground referenced input n Built-in zener on LM2917EP n ± 0.3% linearity typical n Ground referenced tachometer is fully protected from damage due to swings above VCC and belo.

LM2907EP/LM2917EP Enhanced Plastic Frequency to Voltage Converter June 2004 LM2907EP/LM2917EP Enhanced Plastic Frequency to Voltage Converter 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. The op amp/comparator is fully compatible with the tachometer and has a floating transistor as its output. This feature allows either a ground or supply referred load of up to 50 mA.
