High-Accuracy, Wide Common-Mode Range, Bi-Directional CURRENT SHUNT MONITOR Zerø-Drift Series
WIDE COMMON-MODE RANGE: to 80V OFFSET VOLTAGE: ±20V CMRR: 140dB ACCURACY: ±1.4% Gain Error (Max) 0.3V/°C Offset Drift 0.005%/°C Gain Drift (Max) AVAILABLE GAINS: 1000V/V: INA285 QUIESCENT CURRENT: 900A (Max)DESCRIPTION
The INA282 family, which includes the INA284, INA285, and INA286 devices, are voltage output current shunt monitors that can sense drops across shunts at common-mode voltages from to +80V, independent of the supply voltage. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale. These current shunt monitors operate from a single to +18V supply, drawing a maximum 900A of supply current. They are specified over the extended operating temperature range to +125°C, and offered an SOIC-8 package.APPLICATIONS

PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
