The INA233 is a current shunt and power monitor with an I2C/SMBus/PMBus-compatible interface. The device monitors and reports values for current, power, and voltage. The integrated power accumulator can be used for energy or average power calculations. Programmable calibration value, conversion times, and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts. The INA233EVM is a platform for evaluating the performance of the INA233 under various signal, shunt, and supply conditions.
This document gives a general overview of the INA233EVM, and provides a general description of the features and functions to be considered while using this evaluation module.
Table 1-1 summarizes the contents of the INA233EVM kit. Figure 1-1 shows all of the included hardware. Contact the Texas Instruments Product Information Center if any component is missing. TI also highly recommends checking the INA233 product folder on the TI web site at www.ti.com to update to the latest versions of the related software.
