LT1013/LT1014
Quad Precision Op Amp (LT1014)
Dual Precision Op Amp (LT1013)
DescripTion
The LT
®
1014 is the first precision quad operational amplifier
which directly upgrades designs in the industry standard
14-pin DIP LM324/LM348/OP-11/4156 pin configuration.
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
offset null terminals are provided in the quad configuration.
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.
Similarly, the LT1013 is the first precision dual op amp in the
8-pin industry standard configuration, upgrading the per-
formance of such popular devices as the MC1458/MC1558,
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; the output can also swing to within a few millivolts
of ground. Crossover distortion, so apparent on previous
single-supply designs, is eliminated. A full set of specifica-
tions is provided with ± 15V and single 5V supplies.
