A1377 Overview
The Allegro™ A1377 programmable linear Hall-effect sensor IC is designed for applications that require high accuracy and high resolution without promising bandwidth. The A1377 employs segmented, linearly interpolated temperature pensation technology. This improvement greatly reduces the total error of the device across the whole temperature range.
