Interpolation Circuit GC-AIP40

amac logo v4 dunkel

The interpolation circuit GC-AIP40 is used to increase the resolution of incremental position and angle measuring systems with sinusoidal output signals phase-shifted by 90°. The IC is suitable for sensors with a standardized voltage or Power interface, as well as for the direct connection of photodiode arrays and sensor measuring bridges. An adjustable minimum edge separation at the output as well as programmable analog and digital hysteresis enable the IC to be used even with disturbed input signals.
