iC-MHA
ANALOG ANGULAR HALL SENSOR
preliminary
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)
