APDS-9303 is a miniature digital ambient light photo sensor from APD company. It converts light intensity to digital signal output with direct SMBus interface. APDS-9303 adopts a precise photoelectric sensing technology, which features high light responsivity and sensitivity, and can detect extremely weak light. APDS-9303 also has many other advantages, including low power consumption, compact size, and fast response time. APDS-9303 can be widely used in various ambient light sensing applications, such as mobile phones, tablets, laptops, etc.
The APDS-9303 is a miniature ambient‑light photo sensor that converts light intensity to a 16‑bit digital output via an SMBus interface. It contains a broadband (visible + IR) photodiode and a dedicated infrared photodiode, each feeding an integrating ADC.
The device is offered in a 6‑pin ChipLED package (2.60 mm × 2.20 mm × 0.55 mm) and supports programmable gain, integration time, and interrupt thresholds. Typical applications include back‑light control for mobile devices, notebooks, tablets, LCD monitors, automotive instrument clusters, and electronic signage.
