BU9438KV-E2 Overview
This encoder is embedded inside a 64-LQFP package.Packing the encoder in a Tape & Reel (TR) case is recommended to ensure that it is protected.I have mounted this motor encoder in the way of the Surface Mount axis.There are two types of Audio Decoder types that can be identified.This motor encoder is motor encoder of the BU9438 family and is based on that.There is a Surface Mount mount for it.It is equipped with 64 pins on the encoder in question.Using a maximum 85°C value ensures that the encoder reader runs as stable as possible.The minimum working temperature of this rotary encoder must not be less than -40°C.This rotary encoder can operate with a minimum voltage of 3V as long as it has a constant current.As a result, the maximum supply voltage across the converter can be found to be 3.6V.A 1 D/A converter is available on the quadrature encoder as part of its features.
