LM2907 Description
LM2907/LM2917 Frequency to Voltage Converter June 2000 LM2907/LM2917 Frequency to Voltage Converter General .
The LM2907, LM2917 series are monolithic frequency to voltage converters with a high gain op amp/comparator designed to operate a relay, lamp, or othe.
LM2907 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
LM2907 Applications
* The more versatile configurations provide differential tachometer input and uncommitted op amp inputs. With this version the tachometer input may be floated and the op amp becomes suitable for active filter conditioning of the tachometer output. Both of these configurations are available with an ac
