AS5510
Linear Hall Sensor with I²C Output
General Description
The AS5510 is a Linear Hall Sensor with 10 bit resolution and I²C
interface. It can measure absolute position of lateral movement
of a simple 2-pole magnet. Depending on the magnet size, a
lateral stroke of 0.5~2mm can be measured with air gaps
around 1.0mm. To conserve power, the AS5510 may be
switched to a power down state when it is not used. It is
available in a WLCSP and SOIC8 package and qualified for an
ambient temperature range from -30°C to 85°C.
