General Description Figure 1: Added Value of using AS5510 Benefits Highest reliability and durability Ideal for battery powered devices Easy to use High-resolution output Operates in wide magnetic range Smallest form factor AS5510 Linear Hall Sensor with I²C Output 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. Ordering Information and Content Guide appear at end of datasheet. K [ ... ]
