SM3470BB Interpolation Encoder IC OVERVIEW The SM3470B 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). It incorporates a built-in EEPROM for interpolation switching and input signal adjustment functions, providing support for system miniaturization and high-speed input/output signal operation. FEATURES ▪ Interpolation switching function: ×1, 2, 4, 8, 16, 32, 5, 10, 20 (selectable) ▪Adjustment function: Offset adjustment ▪ Supply voltage: 2.7 to 5.
