General Description

This ET2015 is a monolithic bipolar integrated circuit designed to facilitate increased resolution in optical encoder applications by converting the ining sine and cosine signals to an interpolated quadrature digital output at 1 or 5 times the input frequency.

Please refer to the Timing Diagram.

Key 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.
  • Interfaces directly with ET2010 Analog Signal Processor and ET7272 Line Driver.
  • Single supply operation.
  • Handles Sine/Cosine inputs from DC to 125KHz.
  • Sine/Cosine input voltage.
