4/20/2006 -- Targeting mobile, consumer, commercial, and industrial devices, the APDS-9003 analog-output ambient-light photo sensor conserves battery power in portable devices by detecting the amount of ambient light and signaling the device when to turn on or off the display’s backlight and keypad light. In large-panel displays, the device reduces LCD brightness to reduce eye glare and extend the life of the display. Performance feature include operation over the 2.4 to 5.5V supply-voltage range, a 135-mA typical photo current at 100 lux for additional drive to control circuitry, and a –40 to +85°C temperature range. Measuring 1.6×1.5×0.55 mm, the sensor comes in a miniature, lead-free, surface-mount ChipLED-6 package. The APDS-9003 costs 24 cents.
