The INA260 is a digital-output, current, power, and voltage monitor with an
I2C and SMBus™-compatible interface with an integrated precision shunt
resistor. It enables high-accuracy current and power measurements and over-current detection at
common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device
is a bidirectional, low- or high-side, current-shunt monitor that measures current flowing through
the internal current-sensing resistor. The integration of the precision current-sensing resistor
provides calibration-equivalent measurement accuracy with ultra-low temperature drift performance
and ensures that an optimized Kelvin layout for the sensing resistor is always obtained.
The INA260 features up to 16 programmable addresses on the
I2C-compatible interface. The digital interface allows programmable
alert thresholds, analog-to-digital converter (ADC) conversion times, and averaging. To facilitate
ease of use, an internal multiplier enables direct readouts of current in amperes and power in
The device operates from a single 2.7-V to 5.5-V supply, drawing 310 µA (typical) of
supply current. The INA260 is specified over the operating temperature range between –40°C and
+125°C and is available in the 16-pin TSSOP package.
