MagAlpha MA750
Contactless Turning Knob Sensor
DESCRIPTION FEATURES
The MagAlpha MA750 is a robust, contactless,
8-Bit Digital and 12-Bit PWM Output
angle encoder suitable for control buttons and
500kHz Refresh Rate
knobs. The IC detects the absolute angular
7.5mA Supply Current
position of a permanent magnet, typically a
Serial Interface for Data Readout and
diametrically magnetized cylinder attached to
Settings
the rotor.
APPLICATIONS
The output is digital (SPI) or pulse-width
Potentiometer Replacement
modulation (PWM). For usual potentiometer
Knobs
replacement, the PWM signal can be filtered to
Dials
obtain an analog signal.
