AK8859VQ Overview
It is embedded in a 48-LQFP package so that it can be taken anywhere.Packing the encoder in a Bulk case would be a good idea.The mounting of this motor encoder is in the way of Surface Mount.Decoder is a category that can be applied to the type.I think it would work well for the encoder which is connected to the NTSC, PAL axis.Switching power supplies use the 1.7V~3.6V digital power of the optical encoder to provide power to the circuit.This can be achieved by applying a voltage to the analog supply using 1.7V~2V.Ideally, it would be best to package this encoder magnetic in a 48-LQFP (7x7) case.
