14-bit magnetic rotary encoder IC

10 June 2009 Analogue, Mixed Signal, LSI

austriamicrosystems has introduced the AS5163, a magnetic rotary encoder IC specifically designed to satisfy stringent requirements in angle sensing applications where robust IC protection is essential. The device incorporates both +27 V over-voltage protection and -18 V reverse polarity at the supply pins. It also features an intelligent short circuit monitoring function to protect it against damage under short circuit conditions. The AS5163’s single-wire pin can be configured either as a 14-bit digital, 12-bit PWM or ratiometric analog output. In addition, the IC can be customised by the user to cover any system specific angle range. The programming of the desired angle range is achieved by simply setting a start and end position of the rotational movement. The AS5163 is operational over an ambient temperature range from


-40°C to 150°C, is available in a small TSSOP 14 package and operates at 5 V.
