Detailed Description

The device contains a photodiode array, an integrating analog-to-digital converter (ADC), signal processing

circuitry, lux calculation logic, and an I2C serial interface on a single CMOS integrated circuit to provide lux data

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.

† 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.
