DESCRIPTION

•

CHOICE OF GAINS:

The INA210, INA211, INA212, INA213, and INA214

are voltage output current shunt monitors that can

sense drops across shunts at common-mode

voltages from –0.3V to 26V, independent of the

supply voltage. Five fixed gains are available: 50V/V,

100V/V, 200V/V, 500V/V, or 1000V/V. The low offset

of the Zerø-Drift architecture enables current sensing

with maximum drops across the shunt as low as

10mV full-scale.

–

INA210: 200V/V

INA211: 500V/V

INA212: 1000V/V

INA213: 50V/V

INA214: 100V/V

•

QUIESCENT CURRENT: 100μA (max)

SC70 PACKAGE: All Models

THIN QFN PACKAGE: INA210, INA213, INA214

These devices operate from a single +2.7V to +26V

power supply, drawing a maximum of 100μA of

supply current. All versions are specified over the

extended operating temperature range (–40°C to

+125°C), and offered in an SC70 package. The

INA210, INA213, and INA214 are also offered in a

thin QFN package.
