iC-MHA
HALL ANGLE ENCODER
WITH SIN/COS OUTPUTS
The iC-MHA is an integrated Hall device for sensing the angular
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.
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
.
