CPS295HT

CPS295HT

Product name

Ambient Light Sensor (Analog)

Overview

CPS295HT is an ambient light sensor of analog current output type that consists of a photodiode with spectral sensitivity characteristic approximate to luminosity factor, and a current amplifier circuit. The IC enables improvement in visibility of indications, improvement of life of light source, and also reduce power consumption by brightness control and ON/OFF control of light source such as displays.
