DESCRIPTION

The PH5504A2NA1 is an ambient light sensor with a photo diode and current amplifier. This product has spectral

characteristics close to human eye sensitivity and outputs light current proportional to the ambient brightness.

The PH5504A2NA1 can be used to improve the performance and reduce the power consumption of digital equipment

such as FPD-TV sets and mobile phones, by enabling automatic brightness control and automatic switching on and off

of lighting systems.
