OSRAM Opto Semiconductors
SFH 7773 Proximity & Ambient Light Sensor

OSRAM Opto Semiconductors SFH 7773 Proximity & Ambient Light Sensor is a three-in-one digital solution, combining a digital ambient light sensor and a proximity sensor (emitter + detector) within one package. Additionally the sensor provides an I²C-bus interface and an interrupt pin to connect it to a microcontroller. OSRAM Opto Semiconductors SFH 7773 consists of an 850nm infrared (IR) LED and an ultra-low power ASIC which performs the signal processing and provides the I²C-bus interface as well as an interrupt alert function. Additionally the ASIC contains the two photodiodes for proximity resp. ambient light sensing.
