LM111 LM211 - LM311 VOLTAGE COMPARATORS .. . .. . MAXIMUM INPUT CURRENT : 150nA MAXIMUM OFFSET CURRENT : 20nA DIFFERENTIAL INPUT VOLTAGE RANGE : ±30V POWER CONSUMPTION : 135mW AT ±15V SUPPLY VOLTAGE : +5V TO ±15V OUTPUT CURRENT : 50mA D SO8 (Plastic Micropackage) N DIP8 (Plastic Package) DESCRIPTION The LM111, LM211 and LM311 are voltage comparators that have low input currents. They are also designed to operateover a wide range of supplyvoltages : from standard ±15V operational amplifier supplies down to the single +5V supply used for IC logic. Their outputis compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +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 to +14V with a 1mA load current. Thus, these parameters define an error band and take into account the worst-case of voltage gain and input impedance. 2. The response time specified (see definitions) is for a 100mV input step with 5mV overdrive. 3/9 LM111 - LM211 - LM311 TRANSFERT CHARACTERISTICS OUTP UT LIMITING CHARACTERISTICS OUTPUT VOLTAGE (V) Norm al output 50 RL = 1 k Ω VL = +50 V Emitter follower output R L = 600 Ω 40 30 20 Ta mb = +25 C VCC = +30 V 10 140 120 100 -5 0 0.5 P 80 0.4 0.2 20 0.1 0 0 0 5 10 15 OUTP UT VOLTAGE (V) COMMON MODE LIMITS INPUT OFFS ET CURRENT 30 INPUT OFFSET CURRENT ( nA) COMMON MODE LIMITS (V) 0.5 Short circuit curre nt -1 -1.5 0.4 0.2 VCC = –15V 20 Raised 10 Norma l 0 0 10 20 30 40 50 60 70 80 -55 -35 -15 INPUT BIAS CURRENT INPUT BIAS CURRENT (nA) 400 VCC = –15V Raised 300 200 100 0 Norma l -55 5 25 45 65 85 105 TEMPERATURE ( C) TEMPERATURE ( C) -35 -15 5 25 45 65 85 105 TEMPERATURE ( C) 4/9 is 40 1 -0.5 V -CC er d 0.6 oin 0.3 DIFFERENTIAL INPUT VOLTAGE (mV) V+CC ow at s ip 60 0 -1 0.7 Ta mb = +25 C 125 125 POWER DISSIPATION (W) SHORT-CIRCUIT CURRENT (mA) 60 LM111 - LM211 - LM311 EQUIVALENT INPUT OFFS ET ERROR EQUIVALENT INPUT OFFSET ERROR 100 100 10 Maximu m Typica l 1 Tamb = +25 C LM311 EQUIVALENT INPUT OFFSET VOLTAGE (mV) EQUIVALENT INPUT OFFSET VOLTAGE (mV) LM111 LM211 Ta mb = +25 C Maximum 10 Typical VIO = VIO + RS IID VIO = VIO + RS IID 0.1 10k 100k 1M 10k 10M INPUT RESISTANCE (Ω) 1M 10M INPUT RES ISTANCE (Ω) LOW LEVEL OUTP UT S ATURATION VOLTAGE LOW LEVEL OUTPUT SATURATION VOLTAGE 0.8 0.8 0.7 0.6 0.5 Ta mb = -55 C 0.4 0.3 0.2 Tamb = +25 C 0.1 LM311 SATURATION VOLTAGE (V) LM111 LM211 › T a mb = +125 C Tamb = +25 C 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 0 0 10 20 30 40 0 50 10 20 30 40 50 OUTPUT CURRENT (mA) OUTP UT CURENT (mA) INPUT CHARACTE RISTICS 180 INPUT BIAS CURRENT (nA) SATURATION VOLTAGE (V) 100k VCC = –15V Tamb = +25 C 160 140 120 100 80 60 40 20 0-16 -12 -8 -4 0 4 8 12 16 DIFFERENTIALINPUT VOLTAGE (V) 5/9 LM111 - LM211 - LM311 RES P ONS E TIME FOR VARIOUS INPUT OVERDRIVES RES P ONSE TIME FOR VARIOUS INPUT OVERDRIVES 5 20mV 4 3 VCC = –15V Tamb = +25 C 5mV 2 INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) 5 2mV +5 V 1 0 VI 500 Ω - Vo + 100 +5 V 4 VI 3 20mV 2 5mV 1 2mV 0 VCC = –15V Tamb = +2 5 C -100 0 0 0.2 0.4 0.6 0.8 0 TIME ( µ s ) RESP ONS E TIME FOR VARIOUS INPUT OVERDRIVES 5 0 -5 -1 0 VI + - 2 0mV 5 mV Vo 2k Ω VCC - 2 mV -15 100 50 VCC = –15 V Tamb = +25 C 0 0 1 2 TIME ( µ s ) 6/9 3 0.4 0.6 0.8 TIME ( µ s ) 1 5 20mV VCC + 10 0.2 RES PONS E TIME FOR VARIOUS INPUT OVERDRIVES INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) 15 Vo + -50 50 500 Ω - 10 5mV VCC + 5 0 VI 2mV - -5 Vo 2k Ω -10 VCC - -1 5 0 VCC = –15V Tamb = +25 C -5 0 -10 0 4 + 0 1 2 TIME ( µ s) 3 4 LM111 - LM211 - LM311 TYPICAL APPLICATIONS CRYSTAL OSCILLATOR LOW VOLTAGE ADJUSTABLE REFERENCE SUPPLY V CC = +5V R4 2k Ω R1 100k Ω R1 3.9kΩ V CC = +5V R4 500 Ω R3 2 LM111 R2 100k Ω 100kHz C2 10pF 8 7 4 3 2N 1304 Output 1 2 +C 1* 1.5 µF 4 R2 1k Ω * S old ta nta lum 2N 2222 C1 0.1 µF 100KHz FREE RUNNING MULTIVIBRATOR C1 1200pF 7 LM111 Output R3 50k Ω 1 Ω 8 10k 3 TTL INTERFACE WITH HIGH LEVEL LOGIC V CC = +5V R1 240k Ω R3 10kΩ 3 V CC = +5V Input R5 1kΩ R1 20kΩ R3 82kΩ 2 8 LM111 1 3 To TTL logic 4 4 R2 20kΩ 7 LM111 S qua re wa ve output 1 2 R5 1k Ω 8 7 R4 3 9kΩ R2 47k Ω C1 R4 82k Ω 0 to +30Vs wing and +15V thre sholg * TTL or DTL fan-out two AUXILIARY CIRCUITS STROBE INCREASING INPUT STAGE CURRENT OFFSET BALANCING R2 3kΩ 2 3 VCC 7 LM111 6 Q1 2N 2222 2 5 V CC 6 8 TTL s tro be LM11 1 R1 1kΩ 5kΩ 7 2 5 6 8 3 LM11 1 7 3 7/9 LM111 - LM211 - LM311 PM-DIP8.EPS PACKAGE MECANICAL DATA 8 PINS - PLASTIC DIP Millimeters Min.
