description
The LT1013 is a dual precision operational
amplifier featuring low offset voltage temperature
coefficient, high gain, low supply current, and low
noise.
NC – No internal connection
JG OR P PACKAGE
(TOP VIEW)
The LT1013 can be operated from a single 5-V
power supply; the common-mode input voltage
range includes ground, and the output can also
swing to within a few millivolts of ground.
Crossover distortion is eliminated. The LT1013
can be operated with both dual ±15-V and single
5-V supplies.

The LT1013C and LT1013AC, and LT1013D are characterized for operation from 0°C to 70°C. The LT1013I and
LT1013AI, and LT1013DI are characterized for operation from –40°C to 105°C. The LT1013M and LT1013AM,
and LT1013DM are characterized for operation over the full military temperature range of –55°C to 125°C.

APPLICATION INFORMATION
single-supply operation
The LT1013 is fully specified for single-supply operation (V
includes ground, and the output swings to within a few millivolts of ground.
= 0). The common-mode input voltage range
CC–
Furthermore, the LT1013 has specific circuitry that addresses the difficulties of single-supply operation, both
at the input and at the output. At the input, the driving signal can fall below 0 V, either inadvertently or on a
transient basis. If the input is more than a few hundred millivolts below ground, the LT1013 is designed to deal
with the following two problems that can occur:
1. On many other operational amplifiers, when the input is more than a diode drop below ground, unlimited
current will flow from the substrate (V
LT1013, the 400-Ω resistors in series with the input (see schematic) protect the device even when the
terminal) to the input, which can destroy the unit. On the
CC–
input is 5 V below ground.
2. When the input is more than 400 mV below ground (at T = 25°C), the input stage of similar type
A
operational amplifiers saturates and phase reversal occurs at the output. This can cause lock up in
servo systems. Because of a unique phase-reversal protection circuitry (Q21, Q22, Q27, and Q28), the
LT1013 outputs do not reverse, even when the inputs are at –1.5 V (see Figure 24).
This phase-reversal protection circuitry does not function when the other operational amplifier on the LT1013
is driven hard into negative saturation at the output. Phase-reversal protection does not work on amplifier 1
when 2’s output is in negative saturation or on amplifier 2 when 1’s output is in negative saturation.
At the output, other single-supply designs either cannot swing to within 600 mV of ground or cannot sink more
than a few microproamperes while swinging to ground. The all-NPN output stage of the LT1013 maintains its
low output resistance and high gain characteristics until the output is saturated. In dual-supply operations, the
output stage is free of crossover distortion.

comparator applications
The single-supply operation of the LT1013 lends itself for use as a precision comparator with TTL-compatible
output. In systems using both operational amplifiers and comparators, the LT1013 can perform multiple duties.

low-supply operation
The minimum supply voltage for proper operation of the LT1013 is 3.4 V (three Ni-Cad batteries). Typical supply
current at this voltage is 290 µA; therefore, power dissipation is only 1 mW per amplifier.
offset voltage and noise testing
The test circuit for measuring input offset voltage and its temperature coefficient is shown in Figure 30. This
circuit with supply voltages increased to ±20 V is also used as the burn-in configuration.
The peak-to-peak equivalent input noise voltage of the LT1013 is measured using the test circuit shown in
Figure 27. The frequency response of the noise tester indicates that the 0.1-Hz corner is defined by only one
zero. The test time to measure 0.1-Hz to 10-Hz noise should not exceed 10 seconds, as this time limit acts as
an additional zero to eliminate noise contribution from the frequency band below 0.1 Hz.
An input noise voltage test is recommended when measuring the noise of a large number of units. A 10-Hz input
noise voltage measurement correlates well with a 0.1-Hz peak-to-peak noise reading because both results are
determined by the white noise and the location of the 1/f corner frequency.
Current noise is measured by the circuit and formula shown in Figure 28. The noise of the source resistors is
subtracted.
