ET2110

INTERPOLATION DEVICE (Interpolation factors of 1X or 10X) 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 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 400mVpp to 4Vpp on 2.5VDC reference Outputs are NPN Collector with 4K pull-up; sink up to 4mA external load Outputs TTL and CMOS compatible 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.
