3. Detailed Description

The ZOPT2201 contains 4 different photodiode channels for ambient light measurement, UVB energy level measurement, and temperature

compensation. The sensor diodes are arranged in a matrix array. The photodiode currents are converted to digital values by ADCs. The

ZOPT2201 also includes some peripheral circuits such as an internal oscillator, current source, voltage reference, and internal one-time

programmable non-volatile memory (NVM) to store trimming information.
