Data Sheet APDS-9160-003 Digital Proximity and ALS Sensor in Small Aperture Description Features The Broadcom APDS-9160-003 is an integrated ALS and Ambient Light Sensing (ALS) proximity detector with IR LED in an optical module. Light output proportional to light intensity Uses optical coating technology to emulate human The APDS-9160 provides digital ALS and IR sensing, an IR eye spectral response LED, and a complete proximity sensing (PS) system in a Works well under different light source conditions single 8-pin package that is suitable to be used under a High sensitivity in low lux condition. Ideally suited for small aperture of the devices cover windows. The proximity operations behind darkened glass detection feature operates well from bright sunlight to dark 50 Hz/60 Hz light flicker immunity rooms. The APDS-9160 is particularly useful for display Fluorescent light flicker immunity management with the purpose of extending battery life and Programmable interrupt function with upper, lower providing optimum viewing in diverse lighting conditions. thresholds and persists function The APDS-9160 has a wide dynamic range. Current is Programmable LS integration time programmable in 8 different steps. The number of LED Programmable LS gain setting pulses can be configured by using the pulse step, and the Up to 20-bit resolution LED modulation frequency can be set from 60 kHz to Proximity detection (PS) 100 kHz in 5 steps. PS resolution can be varied from 8 bits 100K lux sunlight suppression to 11 bits, and the measurement rate is from 6.25 ms to 400 Up to 11-bit resolution ms. To offset unwanted reflected light from the cover glass, Programmable interrupt function with upper and a PS intelligent cancellation level register allows for an on- lower thresholds and persists function chip subtraction of the ADC count caused by the unwanted Programmable gain setting reflected light from PS ADC output. Supply voltage 1.7V to 3.6V Power management Both the PS and ALS function independently allowing for maximum flexibility in application.
