General Description

The A1128 is a field-programmable, unipolar Hall-effect switch designed for use in high-temperature applications.

This device uses a chopper-stabilization technique to eliminate offset inherent in single-element devices.

The devices are externally programmable.

Overview

A1128 Highly Programmable Hall-Effect Switch.

Key Features

  • Chopper stabilization for stable switchpoints throughout operating temperature range.
  • Externally programmable: ▫ Operate point (through the VCC pin) ▫ Output polarity ▫ Output fall time for reduced EMI in automotive.
