Description

LM2917 devices are monolithic frequency-to-voltage converters with a high gain op amp designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate.

Specifications

  • Ground Referenced Tachometer Input Interfaces Directly With Variable Reluctance Magnetic Pickups
  • Op Amp 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
  • ±0.3% Linearity (Typical)
  • Ground-Referenced Tachometer is Fully Protected From Damage Due to Swings Above VCC and Below Ground
  • Output Swings to Ground For Zero Frequency Input
  • Easy to Use; VOUT = fIN × VCC × R1 × C1
  • Zener Regulator on Chip allows Accurate and Stable Frequency to Voltage or Current Conversion (LM2917)
