Product Description
Product Overview
The AS5262 is a 12-bit magnetic angle position sensor designed for accurate angular measurement over a full 360 turn. This system-on-chip integrates Hall elements, analog front end, digital signal processing, and automotive protection features. It requires a simple two-pole magnet for operation and provides an absolute angle measurement with a resolution of 0.022. The angular output is available as a 12-bit ratiometric analog output. The device operates at a 5V supply voltage with overvoltage protection up to +20V and reverse polarity protection up to 20V.
