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+13.5V supply, drawing a maximum of 900µA of supplycurrent. They are specified over the extended operatingtemperature range (−40°C to +125°C), and are offered ina space-saving SOT23 package.APPLICATIONSDDDDDDDWELDING EQUIPMENTNOTEBOOK COMPUTERSCELL PHONESTELECOM EQUIPMENTAUTOMOTIVEPOWER MANAGEMENTBATTERY CHARGERSRSVIN+NegativeandPositiveCommon−ModeVoltageISV+VIN+5kΩVIN−5kΩLoadA1A2OUT=ISRSRL5kΩINA193−INA198RLPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications of TexasInstrumentssemiconductor products and disclaimers thereto appears at the end of this data sheet.All trademarks are the property of their respective owners.PRODUCTION DATA information is current as of publication date.

INA194INA195, INA196INA197, INA198SBOS307B − MAY 2004 − REVISED JUNE 2004APPLICATIONS INFORMATIONBASIC CONNECTIONFigure 1 shows the basic connection of the INA19x. Theinput pins, VIN+ and VIN−, should be connected as closelyas possible to the shunt resistor to minimize any resistancein series with the shunt resistance.Power-supply bypass capacitors are required for stability.Applications with noisy or high impedance power suppliesmay require additional decoupling capacitors to rejectpower-supply noise. Connect bypass capacitors close tothe device pins.voltage is up to +36V. The output voltage range of the OUTterminal, however, is limited by the voltages on thepower-supply pin.SELECTING RSThe value chosen for the shunt resistor, RS, depends onthe application and is a compromise between small-signalaccuracy and maximum permissible voltage loss in themeasurement line. High values of RS provide betteraccuracy at lower currents by minimizing the effects ofoffset, while low values of RS minimize voltage loss in thesupply line. For most applications, best performance isattained with an RS value that provides a full-scale shuntvoltage range of 50mV to 100mV. Maximum input voltagefor accurate measurements is 500mV.VIN+−16Vto+36VRSIS+2.7Vto+13.5VTRANSIENT PROTECTIONVIN−5kΩV+LoadVIN+5kΩOUTINA193−INA198The −16V to +36V common-mode range of the INA19x isideal for withstanding automotive fault conditions rangingfrom 12V battery reversal up to +36V transients, since noadditional protective components are needed up to thoselevels. In the event that the INA19x is exposed totransients on the inputs in excess of its ratings, thenexternal transient absorption with semiconductor transientabsorbers (zeners or Transzorbs) will be necessary. Useof MOVs or VDRs is not recommended except when theyare used in addition to a semiconductor transient absorber.Select the transient absorber such that it will never allowthe INA19x to be exposed to transients greater than +36V(that is, allow for transient absorber tolerance, as well asadditional voltage due to transient absorber dynamicimpedance). Despite the use of internal zener-type ESDprotection, the INA19x does not lend itself to using externalresistors in series with the inputs since the internal gainresistors can vary up to ±30%. (If gain accuracy is notimportant, then resistors can be added in series with theINA19x inputs with two equal resistors on each input.)OUTPUT VOLTAGE RANGEFigure 1. INA19x Basic ConnectionThe output of the INA19x is accurate within the outputvoltage swing range set by the power supply pin, V+. Thisis best illustrated when using the INA195 or INA198 (whichare both versions using a gain of 100), where a 100mVfull-scale input from the shunt resistor requires an outputvoltage swing of +10V, and a power-supply voltagesufficient to achieve +10V on the output.POWER SUPPLYThe input circuitry of the INA19x can accurately measurebeyond its power-supply voltage, V+. For example, the V+power supply can be 5V, whereas the load power-supply7INA193, INA194INA195, INA196INA197, INA198SBOS307B − MAY 2004 − REVISED JUNE 2004www.ti.comINPUT FILTERINGAn obvious and straightforward location for filtering is atthe output of the INA19x series; however, this locationnegates the advantage of the low output impedance of theinternal buffer. The only other option for filtering is at theinput pins of the INA19x, which is complicated by theinternal 5kΩ + 30% input impedance; see Figure 2. Usingthe lowest possible resistor values minimizes both theinitial shift in gain and effects of tolerance. The effect oninitial gain is given by:Total effect on gain error can be calculated by replacing the5kΩ term with 5kΩ − 30%, (or 3.5kΩ) or 5kΩ + 30% (or6.5kΩ). The tolerance extremes of RFILT can also beinserted into the equation. If a pair of 100Ω 1% resistorsare used on the inputs, the initial gain error will be 1.96%.Worst-case tolerance conditions will always occur at thelower excursion of the internal 5kΩ resistor (3.5kΩ), andthe higher excursion of RFILT − 3% in this case.Note that the specified accuracy of the INA19x must thenbe combined in addition to these tolerances. While thisdiscussion treated accuracy worst-case conditions bycombining the extremes of the resistor values, it isappropriate to use geometric mean or root sum squarecalculations to total the effects of accuracy variations.GainError%+100*100 ǒ5kW5kW)RFILTǓ(1)RSHUNT<
