Applications
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 specifications is provided with ± 15V and single 5V supplies.

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 performance 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.

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.

Note 2: This parameter is guaranteed by design and is not tested. Typical
parameters are defined as the 60% yield of parameter distributions of
individual amplifiers; i.e., out of 100 LT1014s (or 100 LT1013s) typically
240 op amps (or 120 ) will be better than the indicated specification.

applications information
Single Supply Operation
The LT1013/LT1014 are fully specified for single supply
operation, i.e., when the negative supply is 0V. Input
common mode range includes ground; the output swings
within a few millivolts of ground. Single supply operation,
however, can create special difficulties, both at the input
and at the output. The LT1013/LT1014 have specific circuitry
which addresses these problems.
At the input, the driving signal can fall below 0V—inadvertently or on a transient basis. If the input is more
than a few hundred millivolts below ground, two distinct
problems can occur on previous single supply designs,
such as the LM124, LM158, OP-20, OP-21, OP-220,
OP‑221, OP‑420:
a) When the input is more than a diode drop below
ground, unlimited current will flow from the substrate
(V – terminal) to the input. This can destroy the unit. On
the LT1013/LT1014, the 400Ω resistors, in series with the
input (see Schematic Diagram), protect the devices even
when the input is 5V below ground.
10134fd
10. LT1013/LT1014
Applications Information
b) When the input is more than 400mV below ground
(at 25°C), the input stage saturates (transistors Q3 and
Q4) and phase reversal occurs at the output. This can
cause lock-up in servo systems. Due to a unique phase
reversal protection circuitry (Q21, Q22, Q27, Q28), the
LT1013/LT1014’s outputs do not reverse, as illustrated
below, even when the inputs are at –1.5V.
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.
Phase reversal protection does not work on amplifier:
A when D’s output is in negative saturation. B’s and C’s
outputs have no effect.
B when C’s output is in negative saturation. A’s and D’s
outputs have no effect.
C when B’s output is in negative saturation. A’s and D’s
outputs have no effect.
D when A’s output is negative saturation. B’s and C’s
outputs have no effect.
At the output, the aforementioned single supply designs
either cannot swing to within 600mV of ground (OP-20)
or cannot sink more than a few microamperes while swinging to ground (LM124, LM158). The LT1013/LT1014’s
all-NPN output stage maintains its low output resistance and
high gain characteristics until the output is saturated.
In dual supply operations, the output stage is crossover
distortion-free.
Comparator Applications
The single supply operation of the LT1013/LT1014 lends
itself to its use as a precision comparator with TTL compatible output:
In systems using both op amps and comparators, the
LT1013/LT1014 can perform multiple duties; for example,
on the LT1014, two of the devices can be used as op amps
and the other two as comparators.

Low Supply Operation
Test Circuit for Offset Voltage and
Offset Drift with Temperature
The minimum supply voltage for proper operation of the
LT1013/LT1014 is 3.4V (three Ni-Cad batteries). Typical
supply current at this voltage is 290µA, therefore power
dissipation is only one milliwatt per amplifier.
