3 Description
The INA21x are voltage-output, current-shunt
monitors (also called current-sense amplifiers) that
are commonly used for overcurrent protection,
precision-current measurement for system
optimization, or in closed-loop feedback circuits. This
series of devices can sense drops across shunts at
common-mode voltages from –0.3 V to 26 V,
independent of the supply voltage. Six fixed gains are
available: 50 V/V, 75 V/V, 100 V/V, 200 V/V, 500 V/V,
or 1000 V/V. The low offset of the zero-drift
architecture enables current sensing with maximum
drops across the shunt as low as 10-mV full-scale.
These devices operate from a single 2.7-V to 26-V
power supply, drawing a maximum of 100 µA of
supply current. All versions are specified over the
extended
operating
temperature
range
(–40°C to +125°C), and offered in SC70 and UQFN
packages.
