Versatile ambient light sensor can be tuned for optimal human eye sensitivity

Aimed at applications such as automatic light and LCD backlight control, Panasonic's versatile PNJ4K01F ambient light sensor is now stocked by Mouser. The device features a built-in photodiode and current amplifier circuit. It allows for automatic control of display luminosity relative to ambient brightness. With a spectral response similar to that of the human eye, it's possible to design brightness control schemes that are tuned for optimal human sensitivity. This, along with a small package size and low power consumption, makes the PNJ4K01F ideal for applications in mobile electronics, says the company.
