A1425 Description
A1425 High Accuracy Analog Speed Sensor IC with Integrated Filter Capacitor and Dual Zero-Crossing Output Signal .A1425 Features
* ▪ Used in sensing motion of ring magnet or ferrous targets ▪ Integrated filter capacitor ▪ Wide operating temperature range ▪ Operation with magnetic input signal frequency from 20 Hz to 20 kHz ▪ Resistant to EMI ▪ Large effective air gaps ▪ 4.0 to 26.5 V supply operating range ▪ Output compatible wA1425 Applications
* Changes in field strength at the device face, which are induced by a moving target, are sensed by the two integrated Hall transducers. The transducers generate signals that are differentially amplified by on-chip electronics. This differential design provides immunity to radial vibration within the
