I wrote up a piece about AustriaMicrosystems’ 12 bit hall-effect rotary encoder and the ebullient and cheerful Mary Bohenek was nice enough to send me a demo board. This thing is a blast—imagine ...

1. This optimised analogue-conditioning circuit can avoid signal distortion caused by nonlinearities, and guarantee an optimum interface between the encoder and ADC.

RF Solutions has introduced a pair of encoder/decoder ICs for radio-control applications, featuring three independent I/O lines and allowing direct connection of an RF module to simplify design.
