SBOS644C February 2013 – March 2018 INA231
The INA231 is a digital, current-sense amplifier with an I2C- and SMBus-compatible interface. It provides digital current, voltage, and power readings necessary for accurate decision-making in precisely controlled systems. Programmable registers allow flexible configuration for measurement resolution, as well as continuous-versus-triggered operation. Detailed register information is shown in the Register Maps section. See the Functional Block Diagram section for a block diagram of the INA231 device.
