1 Overview

The OPT3004 is an ambient light sensor (ALS) with a digital output integrated circuit. It uses a two-wire interface that works with the I2C protocol making it ideal for many applications. The OPT3004DTSEVM is a platform for evaluating the performance of the OPT3004 under various conditions. The OPT3004DTSEVM consists of two PCBs. The first is the OPTMB EVM board that communicates with the computer, provides power, and sends and receives appropriate digital signals. The second is the OPT3004DTS coupon board, which contains the OPT3004DTS and its support circuitry.
