FEATURES

DESCRIPTION

The INA199 series of voltage output current shunt

monitors can sense drops across shunts at common-

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

supply voltage. Three fixed gains are available:

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.

•

WIDE COMMON-MODE RANGE: –0.3V to 26V

•

OFFSET VOLTAGE: ±150μV (Max)

(Enables shunt drops of 10mV full-scale)

•

ACCURACY

–

±1.5% Gain Error (Max over temperature)

0.5μV/°C Offset Drift (Max)

10ppm/°C Gain Drift (Max)

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

power supply, drawing a maximum of 100μA of

supply current. All versions are specified from –40°C

to +105°C, and offered in both SC70 and thin QFN-

10 packages.

•

CHOICE OF GAINS:

–

INA199A1/B1: 50V/V

INA199A2/B2: 100V/V

INA199A3/B3: 200V/V

•

QUIESCENT CURRENT: 100μA (max)
