Broadcom APDS-9306-065

APDS-9306/APDS-9306-065 is a low-voltage Digital Ambient Light Sensor that converts light intensity to digital signal output with I2C interface. It consists of photodiode, ADC, oscillator and power-on reset to ensure consistent start-up. ADCs convert the photodiode currents to a digital output and the device is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources.

The APDS-9306/APDS-9306-065 approximates the response of the human-eye providing direct read out, where the output count is proportional to ambient light level. Low light functionality enables operation behind darkened glass. The APDS-9306/APDS-9306-065 supports programmable hardware interrupt with hysteresis to respond to events.

APDS-9306 ultra slim form factor with a height of only 0.34mm and APDS-9306-065 with a height of 0.65mm enables the sensor to be designed into space-sensitive applications.
