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 (A and B phases) and a zero point detection digital signal (Z phase).
FEATURES
⪠Interpolation switching function: Ã2, 4, 8, 16 (selectable)
⪠Input frequency: 300kHz (max)
⪠Output frequency: 2.5MHz (max)
⪠Supply voltage: 2.7 to 5.5V
⪠Operating temperature range: â40 to +125°C
⪠Package: QFN24 (size: 4mm à 4mm)
