Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

DEVICE
The device contains a photodiode array, an integrating analog-to-digital converter (ADC), signal processing
circuitry, lux calculation logic, and an I
with a 16-bit output. No external circuitry is required for signal conditioning. The device features power
management modes where the user can select continuous operation, power save mode in which the device
inserts a power saving state between each acquisition, or single-cycle operation in which the device enters a
power-down state after data acquisition. The device has three user-selectable integration times of 100 ms,
200 ms, or 400 ms, allowing the user to adjust the sensitivity of the device.
