LM193-N, LM2903-N, LM293-N, LM393-NSNOSBJ6F –OCTOBER 1999–REVISED DECEMBER 2014
LMx93-N, LM2903-N Low-Power, Low-Offset Voltage, Dual Comparators Features 3 DescriptionThe LM193-N series consists of two independent Wide Supply precision voltage comparators with an offset voltage– Voltage Range: 2.0Vto 36V specification as low as 2.0 mV max for two Singleor Dual Supplies: ±1.0Vto ±18V comparators which were designed specifically to
operate froma single power supply overa wide range• Very Low Supply Current Drain (0.4 mA)— of voltages. Operation from split power suppliesisIndependentof Supply Voltage also possible and the low power supply current drain• Low Input Biasing Current:25 nA is independentof the magnitudeof the power supply• Low Input Offset Current:±5 nA voltage. These comparators also havea unique
characteristicin that the input common-mode voltage• Maximum Offset voltage: ±3 mV range includes ground, even though operated froma• Input Common-Mode Voltage Range Includes single power supply voltage.Ground
Application areas include limit comparators, simple• Differential Input Voltage Range Equalto the analogto digital converters; pulse, squarewave andPower Supply Voltage time delay generators; wide range VCO; MOS clock• Low Output Saturation Voltage: 250 mVat4 mA timers; multivibrators and high voltage digital logic Output Voltage Compatible with TTL, DTL, ECL, gates. The LM193-N series was designedto directly
interface with TTL and CMOS. When operated fromMOS and CMOS logic systems
both plus and minus power supplies, the LM19-N• Availablein the 8-Bump (12 mil) DSBGA Package series will directly interface with MOS logic where• See AN-1112 (SNVA009) for DSBGA their low power drainisa distinct advantage overConsiderations standard comparators. Advantages The LM393 and LM2903 parts are availablein TI’s– High Precision Comparators innovative thin DSBGA package with8 (12 mil) large
bumps.– Reduced VOS Drift Over Temperature Eliminates Need for Dual Supplies
