Additional preview pages of the A19420 datasheet.

The A19420 is an optimized Hall-effect integrated circuit (IC) that measures the speed of rotating targets.

This sensor IC can be used to directly measure ring magnets or be back-biased with a magnet to measure ferrous targets.

Differential Hall-effect sensor measures ring magnets and ferrous targets with inherent stray field immunity.
SolidSpeed Digital Architecture supports advanced algorithms, maintaining pitch and duty cycle accuracy during dynamic air gap disturbances.
Integrated solution includes a capacitor in a single overmolded package.
ISO 26262:2011 ASIL B with integrated diagnostics and certified safety design process.
Two-wire current source output protocol sup.
