iC-MHA
HALL ANGLE ENCODER
WITH SIN/COS OUTPUTS
The iC-MHA is an integrated Hall device for sensing the angular
Features
position of a diametral magnet. With the internal signal condi-
tioning, sine and cosine components of the magnetic field direc-
tion are available on buffered outputs. By using differential Hall
sensors for both sine and cosine sensing, the device is
insensitive to homogenious magnetic stray fields.

Sine/cosine differential outputs
Automatic gain control for 1 Vpp differential signal
amplitude
Operating speed from DC to 20000 RPM
Loss-of-magnet detection and error messaging
•
•
To compensate for variations in magnetic working distance,
temperature and drift, the differential output signals are regu-
lated to 1 Vpp. The outputs are designed to drive differential
resistive loads down to 100 Ω .
