The SM3414 is a reflective absolute linear optical encoder IC.
The absolute code pattern on the scale is read optically and then output via a serial interface. An analog incremental signal can also be output. The device incorporates various adjustment circuits controlled via the serial interface, including adjustments for the absolute code binarization threshold voltage and the incremental signal I/V conversion gain.
