LM2907EP - Enhanced Plastic Frequency to Voltage Converter
Texas Instruments
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.
Key Features
1.
2 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.
