2 Inaddition, 15V specifications are performance of competing devices isachieved at the expense of seriously degrading precision ,noise, speed, and output drive specifications. The LT1077reduces supply current without sacrificing otherparameters. The offset voltage achieved is the lowestof any micropower op amp. Offset current, voltageand current noise, slew rate and gain-bandwidth productare all two to ten times better than on previous micropowerop 1/f corner of the voltage noise spectrum is at results in low frequency ( to 10Hz) noiseperformance which can only be found on devices with anorder of magnitude higher supply LT1077 is completely plug-in compatible (includingnulling) with all industry standard precision op , it can replace these precision op amps in manyapplications without sacrificing performance, yet withsignificant power LT1077 can be operated from one lithium cell or twoNi-Cad batteries.
