AS5050
Low Power 10-Bit Magnetic Rotary Encoder
1 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.
