Quad Precision Op Amp (LT1014)
The LT
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 50 V, drift of 0.3 V/ 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 350 A 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.

... When the input is more than a diode drop below ground, unlimited current will flow from the substrate (V nal) to the input. This can destroy the unit. On the LT1013/ 1014, the 400 schematic diagram), protect the devices even when the input is 5V below ground. ...

... There is one circumstance, however, under which the phase reversal protection circuitry does not function: when the other op amp on the LT1013, or one specific amplifier of the other three on the LT1014, is driven hard into negative saturation at the output.

... U APPLICATIONS INFORMATION Low Supply Operation The minimum supply voltage for proper operation of the LT1013/1014 is 3.4V (three Ni-Cad batteries). Typical supply current at this voltage is 290 A, therefore power dissipation is only one milliwatt per amplifier.
