LT119A/LT319A LM119/LM319 Dual Comparator U DESCRIPTION FEATURES ■ ■ ■ ■ ■ Guaranteed Maximum 0.5mV Input Offset Voltage Input Protection Diodes Operates From Single 5V Supply 25mA Drive Capability 80ns Response Time U APPLICATIONS ■ ■ ■ The LT119A is capable of operation over a supply range from 5V to ±15V and can drive 25mA loads from each open collector output. A separate ground pin allows the LT119A to isolate system grounds. Linear Technology Corporation’s advanced processing, design techniques and reliability make the LT119A/LT319A an ideal choice over previous devices in most comparator applications. Window Detectors High Speed One Shot Relay/Lamp Drivers Voltage Controlled Oscillators U ■ The LT119A is an improved version of the LM119 dual comparator. It features lower input offset voltage and offset current, higher voltage gain, guaranteed common mode rejection, and input protection diodes.

Note 4: Response time specified is for a 100mV input step with 5mV overdrive. Note 5: Inputs are protected with back-to-back 5.6V zener diodes. This limits maximum differential input voltage to ±5V if current is unlimited. Larger differential input drive is allowed if input current is limited to ±5mA with external resistance. 3 LT119A/LT319A LM119/LM319 U W TYPICAL PERFORMANCE CHARACTERISTICS Transfer Function V + + = 5V 25 5 20 4 15 3 10 2 5.0 1 0 –1.0 –0.6 0.2 0.6 –0.2 DIFFERENTIAL INPUT VOLTAGE (mV) 300 200 200 100 0 –6 2 6 –2 DIFFERENTIAL INPUT VOLTAGE (V) 5mV 2 20mV 6 6 5 5 2 0 0 INPUT VOLTAGE (mV) 1 0 –50 –100 50 2mV 4 3 1 0 5mV 20mV VS = 5V RL = 500Ω V ++ = 5V TA = 25°C 100 50 0 100 150 200 250 300 350 TIME (ns) 0 Output Saturation Voltage 50 100 150 200 250 300 350 TIME (ns) 0 –100 50 100 150 200 250 300 350 TIME (ns) Output Limiting Characteristics 120 1.2 TJ = 25°C SUPPLY CURRENT (mA) 5 8 POSITIVE SUPPLY 6 4 NEGATIVE SUPPLY 2 VS = ±15V INPUT OVERDRIVE = 5mV 0 0.6 0.8 0.4 OUTPUT VOLTAGE (V) 1.0 LT119/319 G7 0 15 5 10 SUPPLY VOLTAGE (V) 20 LT119/319 G8 1.0 100 SHORT-CIRCUIT CURRENT AFTER 3 MINUTES 80 0.8 60 0.6 40 0.4 POWER DISSIPATION 20 0 0.2 0 5 10 OUTPUT VOLTAGE (V) 15 LT119/319 G9 0 POWER DISSIPATION (W) 10 SHORT-CIRCUIT CURRENT (mA) 10 15 2mV –50 TJ = 25°C 20 OUTPUT CURRENT (mA) 5mV 0 0 Supply Current TJ = 25°C 4 20mV 2 LT119/319 G6 12 0.2 4 3 LT119/319 G5 25 0 VS = 5V RL = 500Ω V ++ = 5V TA = 25°C 1 LT119/319 G4 0 Response Time for Various Input Overdrives OUTPUT VOLTAGE (V) 4 3 VS = ±15V RL = 500Ω V ++ = 5V TA = 25°C 5 25 45 65 85 105 125 TEMPERATURE (°C) LT119/319 G3 Response Time for Various Input Overdrives OUTPUT VOLTAGE (V) OUTPUT VOLTAGE (V) INPUT VOLTAGE (mV) 2mV 0 – 55 –35 –15 10 LT119/319 G2 Response Time for Various Input Overdrives 5 100 OFFSET LT119/319 G1 6 BIAS 150 50 MAXIMUM DIFFERENTIAL INPUT VOLTAGE –100 –10 0 1.0 VS = ±15V INPUT CURRENT (nA) 6 250 VS = ±15V TA = 25°C 7 INPUT BIAS CURRENT (nA) 30 Input Currents 400 OUTPUT VOLTAGE LOW (V) OUTPUT VOLTAGE HIGH (V) V + + = 36V VS = ±15V RL = 1.4k TA = 25°C 35 Input Characteristics 8 INPUT VOLTAGE (mV) 40 LT119A/LT319A LM119/LM319 U W TYPICAL PERFORMANCE CHARACTERISTICS Common-Mode Limits Supply Current V+ 12 V + = 5V, V – = 0V –0.8 10 SUPPLY CURRENT (mA) COMMON-MODE LIMITS (V) –0.4 VS = ±15V –1.2 –1.6 REFERRED TO SUPPLY VOLTAGES –2.0 1.2 0.8 + – VS = ±15V, V = 5V, V = 0V POSITIVE SUPPLY = 15V 8 6 POSITIVE SUPPLY = 5V, V – = 0V 4 2 NEGATIVE SUPPLY = –15V 0.4 V– – 55 – 35 –15 0 – 55 – 35 –15 5 25 45 65 85 105 125 TEMPERATURE (°C) 5 25 45 65 85 105 125 TEMPERATURE (°C) LT119/319 G11 LT119/319 G10 U TYPICAL APPLICATIONS High Noise Immunity 60Hz Sync Circuit Relay Driver 5V 28V 5V 68k 9 10 – 8 60Hz INPUT 10VP–P (TYP) 6 1/2 LT319A INPUTS 7 + 1N4148 3.3k 20k 9 0.15µF 35V 5 – 10 1/2 LT319A 8 + 6 OUTPUT 7 5 10k LT119/319 TA3 Voltage Controlled Crystal Oscillator With 100PPM Trim Range INPUT 0V TO 5V 100k 10k LT119/319 TA4 AT CUT 18pF, 100kHz 10k 5V MV1405* 4 1000pF 1/2 LT319A 3 5V 10 1k – 1 8 + 1k + 6 1/2 LT319A 9 2 39k 20k OUTPUT 7 – 5 3k 20k 5V 2k LT119/319 TA5 5 LT119A/LT319A LM119/LM319 U TYPICAL APPLICATIONS Voltage Controlled High Speed One Shot 5V 100pF 9 10 – 680Ω 6 1/2 LT319A 2k 8 5V INPUT PULSE + 7408 2 5V OUTPUT 0µs TO 1µs (20ns MINIMUM) 10k 100pF 1k 3 2k 120pF 4 680Ω + 1 1/2 LT319A 7 – 0V TO 1V INPUT 300pF 5 LT119/319 TA6 LM385-1.2 5V 10-Bit Serial Output A/D Converter 5V INPUT 0V TO 3.5V 5V 10k* 20k* LT1004-1.2 4.7k 10k PN4250 4 PN4250 5V 10 – 1 1/2 LT119A 3 1N4148 8 2 + 1000µF † 9 5 –5V 74C04 1k + 1/2 LT119A – 6 DATA OUT 7 1N4148 39k 82k 0.1µF † 2N3904 1N4148 1k 3.9k 15k 1k CONVERT COMMAND INPUT (TTL) *1% FILM –5V † POLYSTYRENE, MOUNT CAPACITORS CLOSE TOGETHER CONVERSION TIME = 10ms * = 1% CAPACITORS ARE POLYSTYRENE MOUNT IN CLOSE PROXIMITY 5V LT119/319 TA7 5 Microsecond Sample-and-Hold with Zero Hold Step 15V + 10µF 1N4148 4.7k 100Ω 3k 2N2907 240Ω 15V 2N2907 2N4931 15V 10 12k 0.003µF † 10k 1 2N2907 3k 2N2222 VOUT – 20k 3 3.3k 9k 1/2 LT119A 2 + –15V 4 1k – 6 8 7 + 9k 15V 3k 1N4148 –15V 6 9 1/2 LT119A 1k 5 INPUT *TRIM FOR ZERO VOLTS OUT WITH ZERO VOLTS IN † POLYSTYRENE CAPACITOR 2pF TO 8pF* 10pF Q VS CLK D 74C74 CLR PRESET 5V 0V SAMPLE HOLD LT119/319 TA8 LT119A/LT319A LM119/LM319 U TYPICAL APPLICATIONS 5kHz to 2MHz V→F Converter 5V 50pF POLYSTYRENE 3.3k 5V 5V 330Ω TTL OUT 5kHz TO 2MHz 470Ω 10k 2k † 20k 4 0V TO 10V 0.01µF 3 2N2369 – 1/2 LT119A + 470Ω 1 22pF 2 10k 220Ω 1M 5V 10k 2k 10 LT1004-1.2 – –5V 6 1/2 LT119A + 7 ALL DIODES 1N4148 † SET SCALE FACTOR 9 0.1µF 8 5 3k LT119/319 TA9 –5V W W SCHEMATIC DIAGRAM R1 3.5k R2 4k V+ R3 4k R6 3k R7 3k Q9 Q4 Q8 Q3 – + C1 18pF Q6 Q2 R4 3k 5.6V INPUTS Q7 R11 13k R5 3k R12 13k R10 170Ω 5.6V Q15 R8 2k Q1 Q5 Q13 R9 18k Q22 R23 4k R22 60Ω R20 3.6k R18 1.9k Q11 R25 600Ω R24 250Ω R19 250Ω Q20 OUTPUT Q14 R13 600Ω Q16 Q12 Q21 TO OTHER SIDE LT119A R15 300 Q10 R16 600Ω R14 2k Q19 Q17 R21 Q18 900Ω R17 3Ω V– Information furnished by Linear Technology Corporation is believed to be accurate and reliable.
