•

WIDE COMMON-MODE RANGE: –14V to 80V

The INA282 family, which includes the INA282,

INA283, INA284, INA285, and INA286 devices, are

•

OFFSET VOLTAGE: ±20mV

voltage output current shunt monitors that can sense

•

CMRR: 140dB

drops across shunts at common-mode voltages from

•

ACCURACY:

–14V to +80V, independent of the supply voltage.

–

±1.4% Gain Error (Max)

The low offset of the Zerø-Drift architecture enables

current sensing with maximum drops across the

–

0.3mV/°C Offset Drift

shunt as low as 10mV full-scale.

–

0.005%/°C Gain Drift (Max)

These current shunt monitors operate from a single

•

AVAILABLE GAINS:

+2.7V to +18V supply, drawing a maximum of 900mA

–

50V/V: INA282

of supply current. They are specified over the

–

100V/V: INA286

extended operating temperature range of –40°C to

+125°C, and offered in an SOIC-8 package.
