1 Overview

Texas Instruments has multiple families of light sensor parts. This EVM user's guide supports all the devices listed above. Each of these parts is a light sensor integrated circuit (IC) with a digital output and works with the I2C protocol; making the device an excellent choice for many applications. The OPTEVM is a platform for evaluating the performance of the multiple light sensor IC under various conditions. The OPTEVM consists of two PCBs. The first PCB is the OPTMB EVM board that communicates with the computer, provides power, and sends and receives appropriate digital signals. The second PCB is the OPTCB coupon board, which contains the light sensor IC for evaluation and support circuitry.
