SM3471AB

The SM3471 is an interpolation IC for encoders. It accepts displacement detection, 2-phase analog signals (A and B phases) and a zero point detection analog signal (Z phase) from an encoder, interpolates the signals by a specified interpolation factor, and outputs corresponding 2-phase digital signals (A and B phases) and a zero point detection digital signal (Z phase).
