General 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.
Key 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.
