APDS-9303 Miniature Ambient Light Photo Sensor with Digital (SMBus) Output Data Sheet Description Features The APDS-9303 is a low-voltage Digital Ambient Light Approximate the human-eye response Photo Sensor that converts light intensity to digital signal Precise Illuminance measurement under diverse light- output capable of direct SMBus interface. Each device ing conditions consists of one broadband photodiode (visible plus Programmable Interrupt Function with User-Defined infrared) and one infrared photodiode. Two integrating Upper and Lower Threshold Settings ADCs convert the photodiode currents to a digital output that represents the irradiance measured on each channel. 16-Bit Digital Output with SMBus at 100 kHz This digital output can be input to a microprocessor where Programmable Analog Gain and Integration Time illuminance (ambient light level) in lux is derived using Miniature ChipLED Package an empirical formula to approximate the human-eye Height 0.55mm response. Length 2.60mm Application Support Information Width 2.20mm The Application Engineering Group is available to 50/60-Hz Lighting Ripple Rejection assist you with the application design associated with Low Active Power (0.6 mW Typical) with Power Down APDS-9303 ambient light photo sensor module.
