The AS5045 absolute analog magnetic rotary encoder integrated circuit from Austriamicrosystems USA has a 12-bit resolution at speeds below 1000 rpm, but operates at higher speeds with reduced resolution. The device provides absolute angle information in a digital format and targets motion-sensing applications that require a resolution below 0.1° of angle. The user can continuously access a serial digital output and pulse-width-modulated (PWM) output at the same time. The angular-position information is in the form of a serial data stream and as a PWM signal with a resolution of 4096 positions per revolution. The model AS5045 has zero-position setting and diagnostic features that are both user-programmable, and the option to cascade several devices in a daisy-chain configuration.
