Overview

LM2917 Frequency to Voltage Converter

The LM2917 is a monolithic frequency to voltage converter with a high gain op amp/comparator designed to switch 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 as the output swings to ground for a zero frequency input.

Features

  • Ground referenced tachometer input connects directly to variable reluctance magnetic pickups
  • Op amp/comparator has floating transistor output
  • 50 mA sink or source to switch relays, solenoids, meters, or LEDs
  • Frequency doubling for low ripple
  • Tachometer has built-in hysteresis with a choice of differential input or ground referenced input
  • Built-in zener
  • +/-0.3% linearity typical
  • Ground referenced tachometer is fully protected from swings above VCC and below ground
