DESCRIPTION  
TheLT®1014isthefirstprecisionquadoperationalamplifier  
which directly upgrades designs in the industry standard

while saving board space and cost, as compared to single  
operational amplifiers.  
TheLT1014’slowoffsetvoltageof50µV, driftof0.3µV/°C,  
offset current of 0.15nA, gain of 8 million, common-mode  
rejection of 117dB and power supply rejection of 120dB  
qualify it as four truly precision operational amplifiers.  
Particularly important is the low offset voltage, since no  
offset null terminals are provided in the quad configura-  
tion. Although supply current is only 350µA per amplifier,  
a new output stage design sources and sinks in excess of  
20mA of load current, while retaining high voltage gain.

APPLICATIONS  
Similarly, the LT1013 is the first precision dual op amp in  
the 8-pin industry standard configuration, upgrading the  
performance of such popular devices as the MC1458/  
1558, LM158 and OP-221. The LT1013’s specifications  
are similar to (even somewhat better than) the LT1014’s.

Both the LT1013 and LT1014 can be operated off a single  
5V power supply: input common-mode range includes  
ground;theoutputcanalsoswingtowithinafewmillivolts  
of ground. Crossover distortion, so apparent on previous  
single-supply designs, is eliminated. A full set of specifi-  
cations is provided with ±15V and single 5V supplies.
