Photo IC diodes
Linear current amplification of photodiode output
The S7183 and S7184 consist of a photodiode and a signal processing circuit for amplifying the photocurrent generated from the photodiode up to 1300 times. Despite a small active area, these photo ICs provide an output nearly equal to that from photodiodes with a 20 × 20 mm active area. Both S7183 and S7184 can be used the same way as a reverse-biased photodiode, and in most cases, they deliver a sufficient output voltage by just connecting a load resistor.
