Unterpremstaetten, Austria austriamicrosystems has expanded its magnetic rotary encoder IC family with the introduction of the AS5046. This 12-bit resolution magnetic rotary encoder detects rotational angle, vertical distance and magnetic tilt. The device can detect vertical distances over several millimeters, making it suitable for contactless, multi-axis human interface devices such as navigational knobs.
The AS5046 is a complete system-on-a-chip, combining both Hall-elements and a signal processor in one package. In addition to rotation detection mode, the AS5046 also supports the detection of magnet tilt with pushbutton functionality, which opens up new opportunities in human interface applications such as joysticks.
The AS5046 device communicates with an external microcontroller over a 2-wire serial interface. For standalone operation, the AS5046 provides a programmable ratiometric analog output. The AS5046 is available in a lead-free SSOP16 package. It can be operated at either 3.3 V or 5.0 V and is specified for -40° to 125°C ambient temperature.
