A1425 - High Accuracy Analog Speed Sensor

Description

The A1425 AC-coupled Hall-effect sensor IC is a monolithic integrated circuit that switches in response to changing differential magnetic fields created by rotating ring magnets and, when coupled with a magnet, by ferrous targets.

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 with both TTL and CMOS logic families.
  • Reverse battery protection.
  • Resistant to mechanical and thermal stress.
  • Accurate true zero-crossing switch point PA.
