Operation from split power supplies is also possible and the low power supply wcurrent drain is independent of the magnitude of the • Wide supply voltage range 2.0V to 32V. • Low supply current drain independent of supply voltage. • Low input biasing current: 25 nA typ. • Low input offset current: 5 nA typ. power supply voltage. 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. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The MIK393 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the MIK393 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. • Low input offset voltage: 2 mV typ. m• Input common-mode voltage range includes GND. .co• Differential input voltage range equal to the power supply voltage. U• Low output saturation voltage. t4• Output voltage compatible with TTL, MOS and eCMOS logic. www.DataShe 1 1 page MIK393 • LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS TYPICAL APPLICATIONS Vcc = 5 V (CONTINUED) ORing THE OUTPUTS Vcc ½ MIK393 ½ MIK393 ZERO CROSSING DETECTOR (SINGLE POWER SUPPLY) ONE-SHOT MULTIVIBRATOR V IN 5,1k 100k 5,1k 1N914 100k 5,1k 1/2 MIK393 20M 10k VO + 0 t0 100pF 1N914 1M 1M 1M VV+cc 10k 1/2 MIK393 0,001µF VO 1ms V+ PW 0 t0 t1 1N914 BI-STABLE MULTIVIBRATOR ½ MIK393 ZERO CROSSING DETECTOR Vcc+ ½ MIK393 Vcc— ONE-SHOT MULTIVIBRATOR WITH INPUT LOCK OUT Vcc ½ MIK393 ½ MIK393 COMPARATOR WITH A NEGATIVE REFERENCE Vcc+ TIME DELAY GENERATOR ++55VVDC R1 R3 R4 R11 R8 ½ MIK393 R14 V03 ½ MIK393 -5V Vcc— R2 ½ MIK393 C1 R15 R5 R12 R9 ½ MIK393 V02 SPLIT-SUPPLY APPLICATIONS MOS CLOCK DRIVER +15V R2 R1 51,0k R2 51,0k R3 10,0k R4 5,1k R5 2,0k R6 3,9k R7 8,2k R8 2,0k R9 6,8k R10 2,4k R11 2,4k C 50,0pF R1 R3 ½ MIK393 R4 C R5 R6 R8 R10 ½ MIK393 R7 ½ MIK393 R9 -15V R11 A MH0025 B R1 = 10 k R2 = 10 k R3 = 15 k R4 = 200 k R5 = 51 k R6 = 51 k R7 = 51 k R8 = 10 k R9 = 10 k R10 = 10 k R11 = 10 M R12 = 10 M R13 = 10 M R14 = 3 k R15 = 3 k R16 = 3 k C1 = 0,001µF R6 R10 R13 ½ MIK393 R7 R16 V01 5 5 Page
