SAA7121H/V2,557 Overview
In the 44-QFP package, the encoder is embedded.When packing the encoder, it is recommended to use a Tray case.There is a Surface Mount-axis mount for this motor encoder.Video Encoder is a classification for the type.Based on SAA7121 family, this motor encoder has been designed.The optical encoder provides switching power through its 3V~3.6V digital power.3.1V~3.5V is responsible for applying the analog supply voltage.Using Surface Mount as a mount, it is attached.The encoder has 44 pins.encoder magnetics should be packed in 44-PQFP (10x10) cases.
