A1388 Datasheet Linear Hall-Effect Sensor

Manufacturer: Allegro MicroSystems

Datasheet Details

New applications for linear output Hall-effect sensors—such as displacement and angular position—require higher accuracy and smaller package sizes.

The Allegro A1388 and A1389 linear Hall-effect sensor ICs have been designed specifically to meet both requirements.

These temperature-stable devices are available in both surface-mount and through-hole packages.

A1388 and A1389 Linear Hall-Effect Sensor ICs with Analog Output Available in a Miniature, Low-Profile Surface-Mount.

5.0 V supply operation.
QVO temperature coefficient programmed at Allegro™ for improved accuracy.
Miniature package options.
High-bandwidth, low-noise analog output.
High-speed chopping scheme minimizes QVO drift across operating temperature range.
Temperature-stable quiescent voltage output and sensitivity.
Precise recoverability after temperature cycling.
Output voltage clamps provide short-circuit diagnostic capabilities.
