AS5055 12bit rotary encoder Datasheet
AS5055
Low power 12 bit magnetic rotary encoder
Preliminary datasheet
1 General Description
The AS5055 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 AS5055 is available in a small QFN 16-pin 4x4x0.85mm package and specified over an operating temperature of -20 to +85°C.
