ET2110 Datasheet (ETIC) - INTERPOLATION DEVICE

ET2110, INTERPOLATION DEVICE

This ET2110 is a monolithic bipolar integrated circuit designed to facilitate increased resolution in optical encoder applications by converting the incoming sine and cosine signals to an interpolated quadrature digital output at 1 or 5 times the input frequency.

ET2110 Features

* Interpolation factor pin selectable (1X/10X)

* Index gating pin selectable (90/180 electrical degrees of interpolated pulse)

* Leading edge of gated index pulse occurs at 270 electrical degrees of analog input cycle, regardless of interpolation factor selected

* Int
