Overview

Product details

The XD2907-14 device is a monolithic frequency-to-voltage converter with a high-gain operational amplifier designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate. The tachometer uses charge pump technology for low multiplier ripple.

Features

● Ground referenced tachometer input interfaces directly to variable reluctance magnetic sensors
● Op amp with floating transistor output
● 50 mA sink/source current for operating relays，solenoids，meters or LEDs Low multiplier ripple
● Tachometer has built-in hysteresis for differential input or ground reference input
● ±0.3% linearity (typical)
● Ground referenced tachometers are not damaged by voltage swings above Vcc and below ground
● Output swings to ground at zero frequency input
● Easy to use; Vout = f in x Vcc x R1 x C1
