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 though operated from a single power supply voltage.

The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC + -1.5V, but either or both inputs can go to +30V without damage Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V bellow the negative power supply, if used). The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained + + 3/11 LM193-LM293-LM393 SUPPLY CURRENT versus SUPPLY VOLTAGE INPUT CURRENT versus SUPPLY VOLTAGE 80 Vi = 0V INPUT CURRENT (nA) Tamb = -55C Tamb = 0C 0.8 Tamb= +25C 0.6 Tamb = +70C 0.4 Tamb = +125C 0.2 R = 0 10 20 30 SUPPLY VOLTAGE (V) 0 Tamb = +125C 10 -1 Tamb = -55C 10 -2 10 -3 Tamb= +25C 10 -2 10 -1 10 0 10 1 10 OUTPUT SINK CURRENT (mA) 6 1 5 4 3 2 1 0 00 50 0 OUTPUT VOLTAGE (V) INPUT VOLTAGE (mV) RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - POSITIVE TRANSITION Input overdrive : 100mV 5mV 20mV 5V 5.1k eI eo Tamb = +25C 0 4/11 INPUT VOLTAGE (mV) SATURATION VOLTAGE (V) 1 Out of saturation 10 0.5 1 1.5 TIME (s) 2 Tamb = -55C i Tamb = 0C Tamb= +25C 40 20 Tamb = +125C Tamb = +70C 10 20 30 SUPPLY VOLTAGE (V) 40 RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - NEGATIVE TRANSITION OUTPUT SATURATION VOLTAGE versus OUTPUT CURRENT 10 60 R = 10 9 0 40 2 OUTPUT VOLTAGE (V) SUPPLY CURRENT (mA) 1 6 5 4 3 2 1 0 0 -50 -100 Input overdrive : 5mV 5V 5.1k 20mV eI eo 100mV Tamb= +25C 0 0.5 1 1.5 TIME (s) 2 LM193-LM293-LM393 TYPICAL APPICATIONS BASIC COMPARATOR DRIVING CMOS 5V VCC = 5V 15k +V(ref) 100kW +V(ref) 1/2 LM193 1/2 LM193 VO & -V(ref) -V(ref) DRIVING TTL LOW FREQUENCY OP AMP 5V 5V 15kW 10kW +V(ref) 1/2 LM193 ~ 1/2 LM193 eo 100kW -V(ref) & LOW FREQUENCY OP AMP (e o = 0V for e I = 0V) A V = 100 5V 5V 1/2 LM193 eI 0.5m F 1kW TRANSDUCER AMPLIFIER Magnetic pick-up 15k W ~ eI & 2N 2222 10kW 3kW 1/2 LM193 0.5m F eo 20MW 100kW eo 1kW 10kW A V = 100 5/11 LM193-LM293-LM393 LOW FREQUENCY OP AMP WITH OFFSET ADJUST ZERO CROSSING DETECTOR (single power supply) 5V 5V Offset Adjust 100kW 5V 1MW R2 Rs eI 100kW 1MW RI 5.1kW 5.1kW eI 15kW 1/2 LM193 ~ 5.1kW 100kW 2N 2222 1/2 LM193 1N4148 0.5m F R1 100kW 20MW 1kW 10kW eo TWO-DECADE HIGH-FREQUENCY VCO VCC 100kW 500pF VCC 3kW 3kW 5.1kW 1/2 LM193 Frequency control voltage input vcontrol 100kW 1/2 LM193 0.01m F 0.1m F Output 1 VCC /2 20kW Output 2 20k W 50kW 1/2 LM193 VCC /2 VCC = +30V +250mV Vcontrol +50V 700 Hz fo 100kHz LIMIT COMPARATOR CRYSTAL CONTROLLED OSCILLATOR VCC (12V) 2R S VCC = 15V 10kW 200kW V(ref) 1/2 LM193 high Lamp RS eI low 6/11 0.1m F 1/2 LM193 ~ 2R S V(ref) 2kW 100kW 1/2 LM193 f = 100kHz 2N 2222 200kW VCC 0 eo LM193-LM293-LM393 SPLIT-SUPPLY APPLICATIONS ZERO CROSSING DETECTOR COMPARATOR WITH A NEGATIVE REFERENCE 15V 15V 5.1k W 5.1kW 1/2 LM193 eI 1/2 LM193 eo eI ~ eo ~ 5V 15V 15V 7/11 LM193-LM293-LM393 PACKAGE MECHANICAL DATA 8 PINS - PLASTIC DIP Millimeters Inches Dimensions Min.
