LT1013/LT1014
Quad Precision Op Amp (LT1014)
Dual Precision Op Amp (LT1013)
DESCRIPTIO
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 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.
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; 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 specifi-
cations is provided with
±15V
and single 5V supplies.
