ky SGS THOMSON = MAXIMUM INPUT CURRENT : 150nA a MAXIMUM OFFSET CURRENT : 20nA DIFFERENTIAL INPUT VOLTAGE RAN +30V a POWER CONSUMPTION : 135mW AT +1 a SUPPLY VOLTAGE : +5V TO +15V a OUTPUT CURRENT : 50mA DESCRIPTION The LM111, LM211 and LM311 are voltage comparators that have low input currents. They are also designed to operate over a wide range of supply voltages : from standard +15V operational amplifier supplies down to the single +5V supply used for IC logic. Their output is compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages +50V at output currents as high as 50mA.

The offset voltage, offset current and bias current specifications apply for any supply voltage from a single +5V supply up to +15V supplies. The offset voltages and offset currents given are the maximum values required to drive the output down to +1V or up ta +14V with a 1mA load current. Thus, these parameters define an error band and take into account ihe worst-case of voltage gain and input impedance. 2. The response time specified (see definitions) is for a 100mV input step with SmV overdrive. k SGS-THOMSON SSF ickosLEcTRONIES 37 309 111-03.TBLLM111 - LM211 - LM311 TRANSFER CHARACTERISTICS OUTPUT LIMITING CHARACTERISTICS 2 07 E 06 S at & 0.5 = o = z 4 5 3 5 o 04 & 3 E < > 3 03 & 5 2 5 5 Temb= + e 0.2 a o Vec=+30V 3 01 5 % . or 0 05 1 0 5 10 6 DIFFERENTIAL INPUT VOLTAGE {mV} OUTPUT VOLTAGE (V) COMMON MODE LIMITS INPUT OFFSET CURRENT Veo z 15. 2 05 5 uw = = -t 5 a oO a 1,5 i Zz 04 \ 3 5 - a = 02 2 ( 8 VE CC So ae aD an go 70 Bo 55_35-16 6 25 45 65 66 106 125 : TEMPERATURE (C) TEMPERATURE (C} INPUT BIAS CURRENT $s & : 2 { = 3 = 3 Qa < a 2 2 0 -85-35-15 6 25 45 85 86 106125 TEMPERATURE (C} 111-04.EPS 47 G7 $GS-THOMSON JH iicRoELECrROMIcs 310SATURATION VOLTAGE (V) EQUIVALENT INPUT OFFSET ERROR LM111 - LM211 - LM311 EQUIVALENT INPUT OFFSET ERROR 100 100 LM111 S Tamb= + 25C 5 .M211 E LM311 5% Ts = a~ vin 3 Maximum wi : g 10 Maximum 5 5 Ee 3 3 z $ 10 > 2 26 Typical 3 Typical 2 2 1 a g 3 6 5 Vio = Vio + R q = + Vio = Vio + Rg lip s 10 10 'S 01 10 k 100 k 1M 10M 10 k 100 k 10M INPUT RESISTANCE (0) INPUT RESISTANCE (0) LOW LEVEL OUTPUT SATURATION VOLTAGE LOW LEVEL OUTPUT SATURATION VOLTAGE 8 LM111 08 25C = => 0.7] LM211 - Tap = + 125C = 67 =" w Q 06 < 06 a 05 =-55 TT c $ 05 04 z oa E 0.3 0.3 0.2 E92 0.1 # 01 0 0 o 10 #20 30 4 0 30 50 OUTPUT CURRENT (mA) OUTPUT CURRENT imA} INPUT CHARACTERISTICS INPUT BIAS CURRENT (nA) 8 88 8 Qo 1612 -8 -4 0 Moc T a sit b = *28C, 12 16 DIFFERENTIAL INPUT VOLTAGE (V) ky7_ SES-THOMSON 111-05.EPS 5/7 311LM111 - LM211 - LM311 RESPONSE TIME FOR VARIOUS RESPONSE TIME FOR VARIOUS INPUT OVEADAIVES INPUT OVERDRIVES Vv, ec =tisv Tomb 7 t25C arm Ny |W eB oO + 5Vv 500 2 Yo INPUT VOLTAGE (mV) QUTPUT VOLTAGE (V) INPUT VOLTAGE (mvV} OUTPUT VOLTAGE (V} 50 P = +25C 0 0.2 0.4 06 08 0 0,2 Oo 06 O08 TIME (us) TIME (us) i RESPONSE TIME FOR VARIOUS RESPONSE TIME FOR VARIOUS _INPUT OVERDRIVES INPUT OVERDRIVES se Ew ss wo E~ ot =u ae w g wi) ce > aa 2 r ho : 2 3 > i 5 a >p a5 { bP 20 be =tis 2 & T amb = +25C 26 0 1 2 > 4 TIME (ust TIME (3) 111-06.EPS a7 G7 $GS-THOMSON yz MICROELECTRONICS 312LM111 - LM211 - LM311 TYPICAL APPLICATIONS .
