SM3473
The SM3473 is an interpolation IC for use with MR sensors. It accepts 2-phase Cos/Sin analog signals from an MR sensor, and outputs a 2-phase incremental pulse with frequency generated by the division of the analog signal by a selectable 1, 2, 4, 8,16× interpolation factor. The analog signal is amplified, with the amplifier gain set by an external resistor voltage divider connected across the supply lines, before interpolation.
