Overview

The TCA9802EVM evaluation module (EVM) allows the user to connect power to and buffer and translate I2C commands to the onboard slave device, TMP102. The EVM allows the designer to load and test different capacitive loading and as the option to replace a series resistor with an inductor to emulate parasitic inductance of cables. Parameters such as rise time, power consumption, and delay times can easily and accurately be evaluated.

Features
  • Evaluate TCA980x against current level-shifters easily
  • Easily evaluate devices with different capacitance or inductance loads
  • Temperature sensor on board to evaluate reliability of communication for different loading conditions
