Linear encoders
Features
Real-time tracking, no-missing-code interpolation
Selectable interpolation factors: x1, x2, x5, x10, x20, x25, x50
100 kHz input frequency at highest resolution
Differential and single-ended PGA inputs
Variable input resistance enables current/voltage conversion
Signal conditioning for offset, amplitude and phase
Controlled 50 mA current source as LED or MR bridge supply
Encoder quadrature output via short-circuit-proof 20 mA push-pull line drivers (RS422)
Fail-safe counting assured by a guaranteed minimum phase distance
Index signal generation at selectable positions
Adjustable index length
Loss-of-signal indicator
Setup via serial EEPROM interface
Sub-system power switch offers reverse polarity protection for the overall system
