SM3471AB Interpolation Encoder IC OVERVIEW 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 (Aand B phases) and a zero point detection digital signal (Z phase). FEATURES ▪ Interpolation switching function: ×2, 4, 8, 16 (selectable) ▪ Input frequency: 300kHz (max) ▪ Output frequency: 2.5MHz (max) ▪ Supply voltage: 2.7 to 5.5V ▪ Operating temperature range: –40 to +125°C ▪ Package: QFN24 (size: 4mm × 4mm) ORDERING INFORMATION Device SM3471AB-G*1 Package 24 pin QFN *1. “-G” option code lead-free package PACKAGE DIMENSIONS 0.2 S A 4.
