 Interpolation Circuit GC-AIP40


 

Characteristics

The Interpolation IC GC-AIP40 is suitable for increasing the resolution of incremental position and angular measuring systems with sine shaped output signals. The IC can be used with the standard voltage signals as well as current signals. Furthermore photo diode arrays and sensor bridges can be connected directly. An adjustable minimum edge distance at the output and a programmable analogue and digital hysteresis enables the use also in case of noisy input signals.
