ET2015 Datasheet - ETIC

ET2015 INTERPOLATION DEVICE

This ET2015 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. Please refer to the Timing Diagram. .

ET2015 Features

* Interpolation factor pin selectable (1X/5X)

* 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

* Inte
