Datasheet

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.
