1 Overview
The INA260 is a high- or low-side current sensor, power, and voltage monitor with a 2-m
Ω
precision
integrated shunt resistor and I
2
C™ interface. The INA260 offers programmable conversion times and
averaging modes, enabling high resolution measurements of the current, voltage, and power dissipation of
the source being monitored. The INA260EVM-PDK, which consists of the INA260EVM and SM-USB-DIG
controller board, is a platform for evaluating the features and performance of the INA260 under various
signal and supply conditions. This document gives a general overview of the INA260EVM-PDK, and
describes the features and functions to be considered when using it.
