12-bit rotary position sensor with digital angle (interface), PWM and ABI output The AS5145B is a contactless magnetic rotary position sensor for accurate angular measurement over a full turn of 360° and over an extended ambient temperature range of -40°C to 150°C. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879°/4096 positions per revolution via a serial bit stream and as a PWM signal. The incremental output (ABI) is preprogrammed for 12 bit.
