Product details

Description

The A1421, A1422, and A1423 are AC-coupled Hall-effect sensor ICs which include monolithic integrated circuits that switch in response to changing differential magnetic fields created by rotating ring magnets or, when coupled with a magnet, by ferrous targets.

Features

Integrated tracking capacitor.
Used for sensing motion of ring magnet or ferrous targets.
Wide operating temperature range.
Operation with magnetic input signal frequency from 20 Hz to 30 kHz.
EMI/ESD-resistant.
Large effective air gaps.
4.0 to 26.5 V supply operating range.
Output compatible with CMOS logic families.
Reverse battery protection.
Resistant to mechanical and thermal stress.
Accurate.
