ic-od, ic-odl optical position-sensitive detector (psd) rev d4, page 2/ 11 description the ic-od/l device is an optical position sensi- tive detector with a monolithic integrated photodiode. the device supersedes one psd and two conven- tional photoelectric detectors, e.g. in motion sensors. constant light and low-frequency variing light are suppressed by a highpass ?lter. a lowpass ?lter reduces high-frequency interference to a minimum. the maximum sensitivity for alternating-light signals (for ac photoelectric currents) is about 100 khz, with a current ampli?cation of typically 48 db. the photoelectric current is partitioned to the two photocurrent ampli?ers according to the position of the light signal. the analogue outputs iac1 and iac2 offer directly the ampli?ed ac photoelectric current.
