They are available with threeoutput voltage scales: 20V/V, 50V/V, and 100V/V. The500kHz bandwidth simplifies use in current control loops.The INA193−INA195 provide identical functions butalternative pin configurations to the INA196−INA198,respectively.The INA193−INA198 operate from a single +2.7V to +18Vsupply, drawing a maximum of 900µA of supply current.They are specified over the extended operatingtemperature range (−40°C to +125°C), and are offered ina space-saving SOT23 package.RSA1A2RLLoadVIN+−16V to +80V+2.7V to +18VNegativeandPositiveCommon−ModeVoltageVIN+VIN−V+ISOUTINA193 −INA198R1R1INA193, INA194INA195, INA196INA197, INA198SBOS307E − MAY 2004 − REVISED AUGUST 2006CURRENT SHUNT MONITOR−16V to +80V Common-Mode Range ! ! www.ti.comCopyright 2004−2006, Texas Instruments IncorporatedPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instrumentssemiconductor products and disclaimers thereto appears at the end of this data sheet.All trademarks are the property of their respective owners."#$% "#&"#'% "#("#)% "#*SBOS307E − MAY 2004 − REVISED AUGUST 2006www.ti.com2ABSOLUTE MAXIMUM RATINGS(1)Supply Voltage +18V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(1)Stresses above these ratings may cause permanent damage.Exposure to absolute maximum conditions for extended periodsmay degrade device reliability. These are stress ratings only, andfunctional operation of the device at these or any other conditionsbeyond those specified is not supported.(2)Input voltage at any pin may exceed the voltage shown if thecurrent at that pin is limited to 5mA.This integrated circuit can be damaged by ESD. TexasInstruments recommends that all integrated circuits behandled with appropriate precautions. Failure to observeproper handling and installation procedures can cause damage.ESD damage can range from subtle performance degradation tocomplete device failure. Precision integrated circuits may be moresusceptible to damage because very small parametric changes couldcause the device not to meet its published specifications.PACKAGE INFORMATION(1)PRODUCT PACKAGE-LEAD PACKAGE DESIGNATOR PACKAGE MARKINGINA193SOT23-5DBVBJJINA193SOT23-5DBVBJJINA194SOT23-5DBVBJIINA194SOT23-5DBVBJIINA195SOT23-5DBVBJKINA195SOT23-5DBVBJKINA196SOT23-5DBVBJEINA196SOT23-5DBVBJEINA197SOT23-5DBVBJHINA197SOT23-5DBVBJHINA198SOT23-5DBVBJLINA198SOT23-5DBVBJL(1)For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI websiteat www.ti.com.PIN ASSIGNMENTSOUTGNDVIN+V+VIN−12354INA193INA194INA195SOT23−5OUTGNDV+VIN−VIN+12354INA196INA197INA198SOT23−5(Pinout #1)(Pinout #2)"#$% "#&"#'% "#("#)% "#*SBOS307E − MAY 2004 − REVISED AUGUST 2006www.ti.com3ELECTRICAL CHARACTERISTICS: VS = +12V Boldface limits apply over the specified temperature range, TA = −40°C to +125°C.All specifications at TA = +25°C, VS = +12V, VIN+ = 12V, and VSENSE = 100mV, unless otherwise noted.INA193, INA194, INA195INA196, INA197, INA198PARAMETER TEST CONDITIONSMIN TYP MAXUNITINPUTFull-Scale Input Voltage VSENSEVSENSE = VIN+ − VIN−0.15 (VS − 0.2)/Gain VCommon-Mode Input Range VCM−16 80 VCommon-Mode Rejection CMR VIN+ = −16V to +80V 80 94 dBOver Temperature VIN+ = +12V to +80V 100 120 dBOffset Voltage, RTI VOS±0.5 2 mVOver Temperature 0.5 3 mVvs Temperature dVOS/dT 2.5 µV/°Cvs Power Supply PSR VS = +2.7V to +18V, VIN+ = +18V 5 100 µV/VInput Bias Current, VIN− pin IB±8 ±16 µAOUTPUT (VSENSE . 20mV)Gain: INA193, INA196 G 20 V/VINA194, INA197 50 V/VINA195, INA198 100 V/VGain Error VSENSE = 20mV to 100mV, TA = 25°C ±0.2 ±1 %Over Temperature VSENSE = 20mV to 100mV ±2 %Total Output Error(1)±0.75 ±2.2 %Over Temperature ±1 ±3 %Nonlinearity Error VSENSE = 20mV to 100mV ±0.002 ±0.1 %Output Impedance RO1.5 ΩMaximum Capacitive Load No Sustained Oscillation 10 nFOUTPUT (VSENSE < 20mV)(4)All Devices −16V ≤ VCM < 0V 300 mVINA193, INA196 0V ≤ VCM ≤ VS, VS = 5V 0.4 VINA194, INA197 0V ≤ VCM ≤ VS, VS = 5V 1
