The Opt101 is a monolithic photodiode with crossover amplifier. The combination of photodiodes and amplifiers on a singlechip eliminates common problems in discrete designs, such as leakage current errors, noise pickup, and stray capacitance gain results. The output voltage increases linearly with light intensity. The amplifier is designed for single or dual operation.
CJMCU-101 is an integrated chip built-in photodiode and transimpedance amplifier , the output voltage increases linearly with the light intensity
Amplifier is a single supply or dual power supply design , so can be used for battery-operated devices
Integrated photodiode and transimpedance amplifier on a single chip , discrete design, can reduce common problems, such as leakage current error , and since the gain peak noise caused by stray capacitance
Photodiode 0.09×0.09inch work in the photoconductive mode , to have a very good linearity and low dark current OPT101 working voltage of 2.7 to 36V, quiescent current of only 120uA .. do not need infrared
