DescripTion
FeaTures
TheLT®1014isthefirstprecisionquadoperationalamplifier
which directly upgrades designs in the industry standard
14-pinDIPLM324/LM348/OP-11/4156pinconfiguration.
It is no longer necessary to compromise specifications,
while saving board space and cost, as compared to single
operational amplifiers.

The LT1014’s low offset voltage of 50µV, drift of 0.3µV/°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
offsetnullterminalsareprovidedinthequadconfiguration.
Althoughsupplycurrentisonly350µAperamplifier,anew
output stage design sources and sinks in excess of 20mA
of load current, while retaining high voltage gain.
