Rotary sensor provides 12-bit resolution

The AS5600 is a programmable, on-axis magnetic rotary position sensor with a 12-bit analogue or PWM output. This contactless system measures the absolute angle of a diametric magnetised on-axis magnet, for contactless potentiometer applications.

The design of the IC/sensor eliminates the influence of any homogenous external stray magnetic fields. The industry-standard I²C interface supports simple user programming of non-volatile parameters without requiring a dedicated programmer. An easy start and stop position programming in a so called “3 wire mode” without a programmer or digital interface is also implemented. The default range of the output is 0 to 360 degrees. The AS5600 can be applied to smaller range, down to 18 degrees, by programming a zero angle (start position) and a maximum angle (stop position). The AS5600 is also equipped with a smart low power mode feature to automatically reduce the power consumption. Its analogue output is ratiometric with respect to VDD. The device costs $1.65 (1000).
