Description
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.
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.
- 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.
