INA2xxEVM Power Monitor Evaluation Modules

Texas Instruments INA2xxEVM Power Monitor Evaluation Modules (EVMs) are easy-to-use platforms for evaluating the main features and performance of the INA228, INA229, INA237, INA238, or INA239. The evaluation module supports current measurements up to 10amps and comes with a graphical user interface (GUI) support for reading and writing to device registers. The Texas Instruments INA228, INA229, INA237, INA238, and INA239 devices are digital power monitors with integrated 20-bit (INA229 and INA228) and 16-bit (INA237, INA238, and INA239) delta-sigma ADCs specifically designed for current-sensing applications. The devices can measure a selectable full-scale differential input of ±163.84mV or ±40.96mV across the shunt with common-mode voltage support from –0.3V to +85V. For the INA228 and INA229, built-in digital accumulation calculates average power, internal die temperature, energy, and charge accumulation. For the INA237, INA238, and INA239, built-in digital accumulation calculates average power and internal die temperature.
