The offset voltage, offset current and bias current specifications apply for anysupply voltage froma single+5V supply up to15V supplies. The offset voltages and offset currents givenare the maximum values required to drive the output down to +1Vor upto +14V with a 1mA loadcurrent. Thus,these parameters define an errorband and take into account the worst-case ofvoltage gain and input impedance. 2. The response time specified (see definitions) is for a 100mV inputstep with5mV overdrive.LM111 - LM211 - LM3113/9OUTPUT VOLTAGE (V)TRANSFERT CHARACTERISTICS-1-500.516050403020100Tamb= +25 C VCC= +30 VNormal outputEmitter follower output RL= 600RL= 1 k VL= +50 VDIFFERENTIALINPUT VOLTAGE (mV)SHORT-CIRCUIT CURRENT (mA)POWER DISSIPATION (W)OUTPUT LIMITING CHARACTERISTICSTamb= +25 CShort circuit currentPow e r dissipat i onOUTPUT VOLTAGE (V)140120100806040200 0510150.70.60.50.40.30.20.10COMMON MODE LIMITS (V)COMMON MODE LIMITS01020304050607080V+CC-0.5-1-1.50.40.2V-CCTEMPERATURE( C)INPUT OFFSET CURRENT ( nA)INPUT OFFSET CURRENT-55-35-155254565851051253020100VCC= 15VRaisedNormalTEMPERATURE( C)INPUT BIAS CURRENT (nA)INPUT BIAS CURRENT4003002001000VCC= 15VRaisedNormal-55-35-15525456585105125 TEMPERATURE ( C)LM111 - LM211 - LM3114/9EQUIVALENT INPUT OFFSET ERRORLM111 LM211 Tamb= +25 CTypicalMaximumVIO= VIO+ RS IID1001010.1INPUT RESISTANCE ()EQUIVALENTINPUT OFFSET VOLTAGE (mV)10k100k1M10MEQUIVALENT INPUT OFFSET ERRORTamb= +25 C LM311TypicalMaximumVIO= VIO+ RS IIDEQUIVALENTINPUT OFFSET VOLTAGE (mV)10k100k1M10M INPUT RESISTANCE ()10010SATURATION VOLTAGE (V)LOW LEVELOUTPUT SATURATION VOLTAGE0.80.70.60.50.40.30.20.10LM111 LM211 Tamb= +125 CTamb= -55 CTamb= +25 COUTPUT CURENT (mA)01020304050SATURATION VOLTAGE (V)LOW LEVELOUTPUT SATURATION VOLTAGEOUTPUT CURRENT (mA)LM311Tamb= +25 C0.80.70.60.50.40.30.20.10 01020304050INPUT BIAS CURRENT (nA)INPUT CHARACTERISTICSVCC= 15V Tamb= +25 CDIFFERENTIALINPUT VOLTAGE (V)-16 -12-8-40481216180160140120100806040200LM111
