APDS-9309 Miniature Ambient Light Photo Sensor 2 with Digital (I C) Output Data Sheet Description Features The APDS-9309 is a low-voltage Digital Ambient Light Approximate the human-eye response Photo Sensor that converts light intensity to digital Precise Illuminance measurement under diverse light- 2 signal output capable of direct I C-bus interface. Each ing conditions device consists of one broadband photodiode (visible Programmable Interrupt Function with User-Defined plus infrared) and one infrared photodiode. Two integrat- Upper and Lower Threshold Settings ing ADCs convert the photodiode currents to a digital 2 output that represents the irradiance measured on each 16-Bit Digital Output with I C Fast-Mode at 400 kHz channel. This digital output can be input to a micropro- Programmable Analog Gain and Integration Time cessor where illuminance (ambient light level) in lux is Miniature ChipLED Package derived using an empirical formula to approximate the o Height 0.65 mm human-eye response. o Length 2.00 mm Applications o Width 2.00 mm Detection of ambient light to control display 50/60 Hz Lighting Ripple Rejection backlighting Low 2.5 V Input Voltage and 1.8 V Digital Output o Mobile devices Cell phones, PDAs, PMP Low Active Power (0.6 mW Typical) with Power Down o Computing devices Notebooks, Tablet PC, Key Mode board RoHS Compliant o Consumer devices LCD Monitor, Flat-panel TVs, Video Cameras, Digital Still Camera Application Support Information Automatic Residential and Commercial Lighting The Application Engineering Group is available to Management assist you with the application design associated with Automotive instrumentation clusters.
