General Description
The AS5050 is a single-chip magnetic rotary encoder IC with low voltage and low power features. It includes 4 integrated Hall elements, a high resolution ADC and a smart power management controller. The angle position, alarm bits and magnetic field information are transmitted over a standard 3-wire or 4-wire SPI interface to the host processor. The AS5050 is available in a small QFN 16-pin 4x4x0.85mm package and specified over an operating temperature of -40ºC to 80ºC.
