SFH7770E6 Datasheet | ams OSRAM

features a mores sensitive proximity sensor (up to five times improved sensitivity) and improved ambient light sensor (sensitive down to 0.03 lx). The document starts with a general introduction to the device, followed by a brief overview on the features (Sec. 2) and operating modes (Sec. 3) of the sensor. The integration and operation of the sensor in an I²C bus environment is described in Sec. 4, whereas Sec. 5 covers the interrupt capabilities of the SFH 7770 E6. Sec. 6 provides a functional description of the sensor. Optical design guidelines and application relevant information are given in Sec. 7 followed by the guidelines for the electrical design in Sec. 8. Finally Sec. 9 presents a sample software code. More general information about ambient light sensing, technical data and I²C bus are available in the following documents: - OSRAM OS general application note on ambient light sensing [1] - SFH 7770 E6 datasheet [2] - I²C bus specification [3] - Driving a LED with an external driver (> 200 m A) application note [4] 2 Introduction The SFH 7770 E6 is a pact device which is designed for simultaneous Fig. 1: Ambient Light and Proximity Sensor SFH 7770 E6. detection of ambient light and proximity of reflecting objects.
