DESCRIPTION
The PH5553A2NA1 is a digital ambient light sensor for I²C bus interfaces and includes a 16-bit AD converter. This
product has spectral characteristics close to human eye sensitivity and outputs digital signals corresponding to the
ambient brightness.
The PH5553A2NA1 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.
FEATURES
• Small and thin SON package
2.55 x 1.56 x 0.55 mm
• Built-in 16-bit AD converter
• I²C bus interface
1.8 V reference supply voltage
• Spectral characteristics close to human eye sensitivity
Peak sensitivity wavelength
550 nm TYP.
• Light source dependence with mounting the device can be reduced by the spectral characteristics adjustment
function from visible region to infrared region.
• The calculation after illuminance output is not necessary by selecting the spectral characteristics from 16 patterns of
those.
• Illuminance detection of wide region can be realized.
Minimum detectable illuminance 0.1 lx
Maximum detectable illuminance 65 535 lx
• Pb-free
APPLICATIONS
• FPD TV sets, displays
• Mobile phones, smartphones
• Notebook PCs, tablet PCs
• DSCs, DVCs
• FA equipment
• Lighting systems, etc.
