| LM111 LM211 - LM311 VOLTAGE COMPARATORS .MAXI .MAXI .DI .POWERCONSUMPTI .SUPPLYVOLTAGE:+5VTO15V .OUTPUTCURRENT:50mA MUM INPUT CURRENT : 150nA MUM OFFSET CURRENT : 20nA FFERENTIAL INPUT VOLTAGE RANGE : 30V ON : 135mW AT 15V N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) 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.

This rating applies for 15V supplies. The positive input voltage limit is 30V above the negative. The negative input voltage limit is equal to the negative supply voltage or 30V below the positive supply, whichever is less. 2/9 LM111 - LM211 - LM311 ELECTRICAL CHARACTERISTICS VCC = 15V, T amb = 25oC (unless otherwise specified) Symbol Vio Parameter Input Offset Voltage (RS 50k) - (note 1) o Tamb = +25 C Tmin.

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 SHORT-CIRCUIT CURRENT (mA) 60 OUTP UT LIMITING CHARACTERISTICS 140 Ta mb = +25 C 120 100 80 60 40 Short circuit curre nt 20 0 0 5 10 15 0.1 0 0.7 Norm al output OUTPUT VOLTAGE (V) POWER DISSIPATION (W) 50 40 Emitter follower output R L = 600 RL = 1 k VL = +50 V P ow r ed is at s ip oin 0.6 0.5 0.4 0.3 0.2 30 20 10 Ta mb = +25 C VCC = +30 V 0 -1 -5 0 0.5 1 DIFFERENTIAL INPUT VOLTAGE (mV) COMMON MODE LIMITS 30 OUTP UT VOLTAGE (V) INPUT OFFS ET CURRENT INPUT OFFSET CURRENT ( nA) V+ CC COMMON MODE LIMITS (V) -0.5 VCC = -15V 20 -1 -1.5 Raised 0.4 10 Norma l 0.2 VCC 0 0 10 20 30 40 50 60 70 80 -55 -35 -15 5 25 45 65 85 105 125 TEMPERATURE ( C) TEMPERATURE ( C) INPUT BIAS CURRENT 400 INPUT BIAS CURRENT (nA) VCC = -15V Raised 300 200 100 Norma l 0 -55 -35 -15 5 25 45 65 85 105 125 TEMPERATURE ( C) 4/9 LM111 - LM211 - LM311 EQUIVALENT INPUT OFFSET ERROR 100 EQUIVALENT INPUT OFFS ET ERROR 100 EQUIVALENT INPUT OFFSET VOLTAGE (mV) EQUIVALENT INPUT OFFSET VOLTAGE (mV) LM111 LM211 Ta mb = +25 C 10 Maximu m Tamb = +25 C LM311 Maximum 10 Typical 1 Typica l VIO = VIO + RS IID 0.1 10k VIO = VIO + RS IID INPUT RESISTANCE () 100k 1M 10M 10k 100k 1M 10M INPUT RES ISTANCE () LOW LEVEL OUTPUT SATURATION VOLTAGE 0.8 LOW LEVEL OUTP UT S ATURATION VOLTAGE 0.8 SATURATION VOLTAGE (V) 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 SATURATION VOLTAGE (V) LM111 LM211 T a mb = +125 C LM311 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 Tamb = +25 C Ta mb = -55 C Tamb = +25 C 0 10 20 30 40 50 0 10 20 30 40 50 OUTP UT CURENT (mA) OUTPUT CURRENT (mA) INPUT CHARACTE RISTICS 180 INPUT BIAS CURRENT (nA) 160 140 120 100 80 60 40 20 0-16 -12 -8 -4 0 VCC = -15V Tamb = +25 C 4 8 12 16 DIFFERENTIALINPUT VOLTAGE (V) 5/9 LM111 - LM211 - LM311 RES P ONSE TIME FOR VARIOUS INPUT OVERDRIVES 5 5 RES P ONS E TIME FOR VARIOUS INPUT OVERDRIVES +5 V VI + 500 Vo INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) 4 3 2 1 0 100 50 0 20mV 5mV 2mV VI - VCC = -15V Tamb = +25 C INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) 4 3 2 1 20mV 5mV 2mV +5 V 500 Vo + 0 VCC = -15V Tamb = +2 5 C 0 0.2 0.4 0.6 0.8 -50 -100 0 0.2 0.4 0.6 0.8 TIME ( s ) RESP ONS E TIME FOR VARIOUS INPUT OVERDRIVES 15 TIME ( s ) RES PONS E TIME FOR VARIOUS INPUT OVERDRIVES 1 5 20mV INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) INPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) VCC + VI + Vo 2k VCC - 10 5 0 -5 -1 0 -15 100 50 0 0 1 2 0mV 5 mV 2 mV 10 5 0 -5 -10 -1 5 0 -5 0 -10 0 5mV 2mV VI + - VCC + Vo 2k VCC - VCC = -15 V Tamb = +25 C 2 3 4 VCC = -15V Tamb = +25 C 0 1 2 3 4 TIME ( s ) TIME ( s) 6/9 LM111 - LM211 - LM311 TYPICAL APPLICATIONS CRYSTAL OSCILLATOR LOW VOLTAGE ADJUSTABLE REFERENCE SUPPLY V CC = +5V R4 500 R1 100k V CC = +5V R4 2k R1 3.9k 2 R2 100k LM111 3 1 C1 0.1 F 100kHz C2 10pF 8 7 4 R3 50k 3 2N 1304 8 10k LM111 7 1 4 Output +C 1* 1.5 F * S old ta nta lum R3 Output 2 R2 1k 2N 2222 100KHz FREE RUNNING MULTIVIBRATOR R1 20k V CC = +5V TTL INTERFACE WITH HIGH LEVEL LOGIC Input V CC = +5V C1 1200pF R5 1k 3 R3 10k 8 LM111 7 1 4 S qua re wa ve output R1 240k R3 82k 2 8 LM111 3 4 1 To TTL logic 7 R5 1k 2 R2 20k R4 3 9k C1 R2 47k R4 82k 0 to +30Vs wing and +15V thre sholg * TTL or DTL fan-out two AUXILIARY CIRCUITS STROBE INCREASING INPUT STAGE CURRENT OFFSET BALANCING R2 3k 2 LM111 3 Q1 2N 2222 R1 1k 6 TTL s tro be 7 VCC 2 5 6 8 LM11 1 3 7 5k V CC 2 56 8 LM11 1 3 7 7/9 LM111 - LM211 - LM311 PACKAGE MECANICAL DATA 8 PINS - PLASTIC DIP Dim.
