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.
