3 Description

The INA199 series of voltage-output, current-shunt

monitors (also called current-sense amplifiers) are

commonly used for overcurrent protection, precisioncurrent

measurement for system optimization, or in

closed-loop feedback circuits. This series of devices

can sense drops across shunt resistors at commonmode

voltages from –0.3 V to 26 V, independent of

the supply voltage. Three fixed gains are available:

50 V/V, 100 V/V, and 200 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 from –

40°C to 125°C, and offered in both SC70-6 and thin

UQFN-10 packages.
