WIDE SINGLE SUPPLY VOLTAGE RANGE OR DUAL SUPPLIES +2V TO +36V OR 1V TO 18V VERY LOW SUPPLY CURRENT (0.4mA) INDEPENDENT OF SUPPLY VOLTAGE (1 mW/comparator at +5V) LOW INPUT BIAS CURRENT : 25nA TYP LOW INPUT OFFSET CURRENT : 5nA TYP LOW INPUT OFFSET VOLTAGE : 1mV TYP INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GROUND LOW OUTPUT SATURATION VOLTAGE : 250mV TYP. (IO = 4mA) DIFFERENTIAL INPUT VOLTAGE RANGE EQUAL TO THE SUPPLY VOLTAGE TTL, DTL, ECL, MOS, CMOS COMPATIBLE OUTPUTS D SO8 (Plastic Micropackage) N DIP8 (Plastic Package) P TSSOP8 (Thin Shrink Small Outline Package) DESCRIPTION These devices consist of two independent low power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even thoughoperatedfrom a single power supply voltage.

At out put switch point, VO 1.4V, R S = 0 with VC C+ fr om 5V to 30V and over the full input common-mode range (0V to V CC + 1.5V). 3. The direct ion of the input current is out of the IC due to the PNP i nput stage. T his cur rent is essent ial ly const ant, independent of the state of the output, so no loadi ng charge exists on the reference or input l ines. 4. The input common-mode volt age of either input si gnal vol tage shoul d not be all owed to go negat ive by more than 0.3V . The upper end of the common-mode vol tage range is VC C + -1.5V , but either or bot h inputs can go to +30V wi thout damage. 5. The response ti me specifi ed is for a 100mV i nput step w it h 5mV overdr ive. For l arger over drive signal s 300ns can be obtained. 6. Posit ive excursions of i nput voltage may exceed the power suppl y level. A s l ong as the other voltage remai ns within the common-mode range the compar ator wil l provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V below the negat ive power supply, if used). 3/10 LM193 - LM293 - LM393 SUPPLY CURRENT versus SUPPLY VOLTAGE 80 Tamb = -55C INPUT CURRENT (nA) Vi = 0V Tamb = 0C 0.8 T = +25C 0.6 T amb = +70C 0.4 Tamb = +125C 0.2 RL = 0 10 20 30 SUPPLY VOLTAGE (V) 10 0 -1 -2 Tamb = +25C -3 10 -2 10 -1 10 0 10 20 Tamb = +125C 0 OUTPUT VOLTAGE(V) SATURATION VOLTAGE(V) 1 Tamb = -55C 10 1 Tamb = +25C 40 10 20 30 SUPPLY VOLTAGE (V) 10 2 OUTPUT SINK CURRENT (mA) 6 5 4 3 2 1 0 0 -50 -100 Input overdrive : 5mV OUTPUT VOLTAGE (V) INPUT VOLTAGE(mV) 4/10 6 Input overdrive : 100mV 5 4 5mV 3 2 20mV 1 0 100 Tamb = +25C 50 0 0.5 1 1.5 TIME (s) eI eo 100mV Tamb = +25C 0 0.5 5V 5. 1 k e 5V 5.1k 20mV RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - POSITIVE TRANSITION 0 40 RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - NEGATIVE TRANSITION Tamb = +125C 10 Tamb = 0C 40 Out of saturation 10 Tamb = -55C Tamb = +70C OUTPUT SATURATION VOLTAGE versus OUTPUT CURRENT 10 9 R i = 10 60 INPUT VOLTAGE(mV) SUPPLYCURRENT (mA) 1 INPUT CURRENT versus SUPPLY VOLTAGE I eo 2 1 1.5 TIME (s) 2 LM193 - LM293 - LM393 TYPICAL APPLICATIONS BASIC COMPARATOR DRIVING CMOS VCC 5V = 5V 15k 100k +V(re f ) +V (ref) 1/2 LM193 VO -V (ref) DRIVING TTL 1/2 LM193 & -V(re f ) LOW FREQUENCY OP AMP 5V 5V 15k 10k 1/2 LM193 +V(r ef ) ~ 1/2 LM193 e I & -V(r ef ) eo 100k & 0.5 F 1k A V = 100 LOW FREQUENCY OP AMP TRANSDUCER AMPLIFIER (e o = 0V for e I = 0V) 5V 5V Magnetic pick-up 10k 3k 15k ~ eI 1/2 LM193 0.5F eo 20M 100k 1k 1/2 LM193 2N 2222 eo 10k A V = 100 5/10 LM193 - LM293 - LM393 LOW FREQUENCY OP AMP WITH OFFSET ADJUST ZERO CROSSING DETECTOR (SINGLE POWER SUPPLY) 5V 5V 100k Offset Adjust 5V 1M R2 Rs eI 100k 1M RI 15k eI 1/2 LM193 0.5F R1 100k ~ 5.1k 100k 5.1k 5.1k 1/2 2N 2222 LM193 1N4148 20M 1k 10k eo TWO DECADES HIGH FREQUENCY VCO VCC 100k 500pF Fre que ncy co ntrol voltage input vcontrol 3k 0.01 F 0.1 F 20k VCC 3k 5.1k 1/2 LM193 10k 100k 1/2 LM193 Output 1 VCC /2 Output 2 20k 50k VCC /2 1/2 LM193 VCC = +30V +250mV Vcontrol +50V 700 Hz fo 100kHz LIMIT COMPARATOR CRYSTAL CONTROLLED OSCILLATOR VCC = 15V V CC (12V) 2R 200k 10k S V (ref) 2k 100k 1/2 hig h LM193 Lamp RS e I 0.1F 1/2 LM193 ~ f = 100kHz low 6/10 S 200k 2N 2222 193-17.EPS 2R V (ref) 1/2 LM193 VCC 0 eo LM193 - LM293 - LM393 SPLIT-SUPPLY APPLICATIONS ZERO CROSSING DETECTOR COMPARATOR WITH A NEGATIVE REFERENCE 15V 15V 5.1k eI ~ 1/2 LM193 5.1k 1/2 LM193 eo eI ~ eo 5V 15V 15V 7/10 LM193 - LM293 - LM393 PM-DIP8.EPS PACKAGE MECHANICAL DATA 8 PINS -PLASTIC DIP A a1 B b b1 D E e e3 e4 F i L Z 8/10 Min.
