Need to detect light levels for a project? The OPT101 is a handy little chip that combines a photodiode and a transimpedance amplifier on one chip. It outputs a voltage proportional to light intensity. Operates on a single power supply from 2.7V to 36V, has a built-in 1MΩ feedback resistor, and offers a bandwidth of about 14kHz. Responsive at 0.45 A/W (650nm wavelength). Super low quiescent current (120µA). Great for DIY electronics, robotics, light meters, barcode scanners, proximity sensing, medical instruments, or any application where you need to measure light. A professional-grade component for hobbyists and engineers alike.
