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.
