Product Description
Product Overview
The AS5045 is a 12-bit programmable magnetic rotary position sensor designed for accurate 360 angular measurement. This system-on-chip integrates Hall elements, analog front end, and digital signal processing, requiring only a simple two-pole magnet for operation. It provides absolute angle measurement with a resolution of 0.0879, outputting digital data via a serial bit stream or a PWM signal. The device supports 3.3V or 5V supplies and features failure detection modes, diagnostic capabilities, and a wide operating temperature range.
