iC-MHA

ANALOG ANGULAR HALL SENSOR

Rev B2, Page 2/10

DESCRIPTION

The iC-MHA is a position sensor with integrated Hall

sensors for scanning a permanent magnet. The sig-

nal conditioning unit generates constant-amplitude

sine and cosine voltages that can be used for angle

calculation.

Sine and cosine signals are availabe via line driver

outputs (100 Ω load)
