KMï¼ï¼ï¼ï¼ is the first LSI in the world which has realized the 16 interpolation digital output (64 edges per one
sine period) proportioned to the input phase electrically for the encoder application. KM1102 uses the theory
of " a Phase Voltage Conversion Method by Resistor ladder" and so well organized, high planerized precious
poli-silicon Resistor arrays results in the high resolution "Photo-Encoder","Magnetic Encoder" and "Laser
Encoder".
