austriamicrosystems AG AS5134

The AS5134 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360º. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8.5 bit = 360 positions per revolution.

GENERAL DESCRIPTION

To measure the angle, only a simple two-pole magnet, rotating over the center of the chip is required. This digital data is available as a serial bit stream and as a PWM signal. In addition to the angle information, the strength of the magnetic field is also available as a 6-bit code. Data transmission can be configured for 1-wire (PWM), 2-wires (DCLK, DIO) or 3-wires (DCLK, DIO, CS). A software programmable (OTP) zero position simplifies assembly as the zero position of the magnet does not need to be mechanically aligned. A Power Down Mode together with fast startup and measurement cycles allows for very low average power consumption. 2 Key
