ET2015 Datasheet | ETIC

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 range 400m Vpp to 4Vpp on 2.5VDC reference - Outputs are NPN Collector with 4K pull-up; sink up to 4m A external load - Outputs TTL and CMOS patible 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.
