OSRAM SFH 7776 Ambient Light and Proximity Sensor

OSRAM SFH 7776 Ambient Light & Proximity Sensor

OSRAM Opto Semiconductors SFH 7776 Ambient Light and Proximity Sensor with Integrated 850nm Emitter controls backlighting and touch functions in mobile devices. SFH 7776 features a detection range of up to 160mm and a programmable pulse current up to 200mA. The high sensitivity of this OSRAM detector eliminates the need for lenses to bundle the emitted infrared light and allows it to achieve a small height of only 1.35mm. SFH 7776 achieves extremely low power, consuming only 0.8mA in standby mode. The device also provides high ambient light sensitivity with a detection limit of 0.002 lux. This high sensitivity means the device can be used even behind dark casing panels.
