The photo IC is an intelligent optical sensor with diverse functions and integrating a photodiode with signal processing IC in the same package. Phototransistors are also provided.
Photo IC receivers and emitters for plastic optical fiber communications. Our receiver line-up includes monolithic IC devices integrated with a PIN photodiode and analog amplifier.
Photo IC diodes with spectral response characteristics close to human visual sensitivity. These are as easy to use as a photodiode, yet offer high current output similar to phototransistors.
This is a CMOS photo IC combining a current-to-frequency converter and photodiode. This photo IC outputs an oscillating frequency (duty ratio 50 %) proportional to input intensity.
This is a digital color sensor sensitive to red (λp=615 nm), green (λp=540 nm) and blue (λp=465 nm) light. Detected signals are output serially as 12-bit digital data.
Phototransistors amplify the current generated by the input of light. Compared to photodiodes, a large output current can be derived even from a small active area.
These sensors are designed specifically for flame detection (flame eye) in oil-fired hot water boilers and heaters. These sensors incorporate a photo IC diode instead of conventional CdS cells.
