ROHM Semiconductor BU27030NUC Ambient Light Sensor

ROHM Semiconductor BU27030NUC Ambient Light Sensor is optimized for obtaining ambient light data for adjusting the display and backlight power of TVs and smartphones. This device is capable of detecting a very wide range of illuminance. The BU27030NUC features inherent 50Hz/60Hz light noise rejection and excellent IR-cut characteristics for high robustness at high sensitivity. This sensor communicates via a digital serial I²C bus interface with f/s mode support.

The ROHM Semiconductor BU27030NUC Ambient Light Sensor is offered in a compact WSON008X2120 package, ideal for space-constrained applications.
