Product Information

Back to top
The iC-OF device is an optoelectronic detector IC for linear and angle measuring systems, such as shaft encoders.

Photodiodes, amplifiers, comparators and TTL-compatible push-pull output drivers are integrated monolithically. Each of the 3 tracks is evaluated differentially; there are also analog outputs available.

The outputs are protected against ESD and short-circuit damage.
