DESCRIPTION
The INA216 is a high-side voltage output current
shunt monitor that can sense drops across shunts at
common-mode voltages from +1.8V to +5.5V. Four
fixed gains are available: 25V/V, 50V/V, 100V/V, and
200V/V. The low offset of the Zerø-Drift architecture
enables current sensing with maximum drops across
the shunt as low as 10mV full-scale, or with wide
dynamic ranges of over 1000:1.
These devices operate from a single +1.8V to +5.5V
power supply, drawing a maximum of 25μA of supply
current. The INA216 series are specified over the
temperature range of 40°C to +125°C, and offered
in a chip-scale package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2) VIN+ and VINare the voltages at the IN+ and INpins, respectively.
(3) Input voltage at any pin may exceed the voltage shown if the current at that pin is limited to 5mA.
