LM2917 Frequency to Voltage Converter - (AD2415)

Description:

The LM2917 is a monolithic frequency-to-voltage converter with high gain, an Op-Amp/Comparator designed to control a relay, lamp, or other load when the input frequency exceeds a preset value. The tachometer uses a charge pump technique and offers a dual frequency for low ripple; it has complete input protection and an output that drops to ground when the input is zero Hz.

Features:

- Operational amplifier / comparator with transistor

- 50mA source to drive relays, solenoids or LEDs

- Built-in Zener
