The CJMCU-101 is an integrated photodiode and transimpedance amplifier with a chip inside. Putting integrated photodiodes and transimpedance amplifiers on a single chip can prevent common problems in discrete designs. Such as leakage current error, noise, and gain peaks caused by stray capacitance. One advantage of the sensor is that the amplifier is a single or dual power supply design, which can work on battery equipment. When the photodiode works in the photoconductive mode, it has good linearity and a low dark current.

The sensor can be used on smoke detectors, currency changers, and barcode scanners. It can also be applied to medical instrumentation, laboratory instrumentation, and photographic analyzers.
