描述
The RAA3064002GFP (hereinafter together referred to as “this IC”) is resolver-to-digital converters which are intended for use with single-phase excitation, two-phase output type resolver sensors (angle sensors). The resolver sensor outputs analog signals (electrical angle information) which are proportional to the angle of the mechanical rotation of the resolver. This IC converts these analog signals to digital signals. This IC can be connected to either of two types of resolver sensor.
