Overview
The INA233AIDGST is a high-precision current, voltage, and power monitor produced by Texas Instruments. This device features an I2C-, SMBus-, and PMBus-compatible interface, making it versatile for various applications requiring accurate power monitoring. The INA233AIDGST operates from a single 2.7-V to 5.5-V supply and can sense bus voltages from 0 V to 36 V, independent of the supply voltage. It is designed for high accuracy with a maximum gain error of 0.1% and a maximum offset voltage of 10 µV. The device includes an integrated power accumulator for energy and average power calculations and supports programmable calibration, conversion times, and averaging options.
