The LT1013x devices 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 LT1013x can be operated
with both dual ± 15-V and single 5-V supplies.
The LT1013C and LT1013D are characterized for
operation from 0°C to 70°C. The LT1013DI is
characterized for operation from −40°C to 105°C. The
LT1013M,
LT1013AM,
and
LT1013DM
are
characterized for operation over the full military
temperature range of −55°C to 125°C.

For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application
report.
Maximum power dissipation is a function of TJ(max), RθJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) − TA )/ RθJA. Operating at the absolute maximum TJ of 150°C can affect reliability. Due to variation in
individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power
levels slightly above or below the rated dissipation.
The package thermal impedance is calculated in accordance with JESD 51-7.
RθJC(top) and RθJC(bot)thermal impedances are calculated in accordance with MIL-STD-883 for LCCC and CDIP

7 Detailed Description
7.1 Overview
The LT1013x device is a dual operational amplifier with low natural VIO without programming memory that can be
erased. There are no side effects from active VIO correction used by other op amps. The LT1013x has built-in
protection for input voltage below VCC–. However, an external resistance must be add to protect the LT1013x
from input voltage greater than VCC+.

7.3 Feature Description
7.3.1 Input Resistors
For voltages less than VCC–, a pair of 400-Ω resistors limit input current. These resistors have parasitic diodes to
VCC+. Therefore, external series resistance is needed if input voltage exceed VCC+
7.3.2 Output Stage
High output is provided by Q33 emitter for low output impedance. Q26 provides active current limiting for
sourcing current.
Low output is provided by Q34 collector for lower output voltage near VCC– rail. Q24 provides active current
limiting for sinking current.

Feature Description (continued)
7.3.3 Low-Supply Operation
The minimum supply voltage for proper operation of the LT1013x is 3.4 V (three NiCad batteries). Typical supply
current at this voltage is 290 µA; therefore, power dissipation is only 1 mW per amplifier.
7.3.4 Output Phase Reversal Protection
The LT1013x is fully specified for single-supply operation (VCC− = 0). The common-mode input voltage range
includes ground, and the output swings to within a few millivolts of ground.
Furthermore, the LT1013x 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 LT1013x 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 flows from the substrate (VCC− terminal) to the input, which can destroy the unit. On the LT1013x,
the 400-Ω resistors in series with the input protect the device, even when the input is 5 V below ground.
2. When the input is more than 400 mV below ground (at TA = 25°C), the input stage of similar operational
amplifiers saturates, and phase reversal occurs at the output. This can cause lockup in servo systems.
Because of unique phase-reversal protection circuitry (Q21, Q22, Q27, and Q28), the LT1013x 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 LT1013x is
driven hard into negative saturation at the output. Phase-reversal protection does not work on amplifier 1 when
amplifier 2 output is in negative saturation nor on amplifier 2 when amplifier 1 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 micro amperes while swinging to ground. The all-npn output stage of the LT1013x 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.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LT1013x operational amplifiers are useful in a wide range of signal conditioning applications where high DC
accuracy is needed.
8.2 Typical Application
A typical application for an operational amplifier in an inverting amplifier. This amplifier takes a positive voltage
on the input and makes it a negative voltage of the same magnitude. In the same manner, it also makes negative
voltages positive.

Figure 27. Application Schematic
8.2.1 Design Requirements
The supply voltage must be chosen such that it is larger than the input voltage range and output range. For
instance, this application scales a signal of ±0.5 V to ±1.8 V. Setting the supply at ±12 V is sufficient to
accommodate this application.
8.2.2 Detailed Design Procedure
Determine the gain required by the inverting amplifier using Equation 1 and Equation 2:
(1)
(2)
Once the desired gain is determined, choose a value for RI or RF. Choosing a value in the kΩ range is desirable
because the amplifier circuit will use currents in the milliamp range. This ensures the part does not draw too
much current. This example chooses 10 kΩ for RI, which means 36 kΩ is used for RF. This was determined by
Equation 3.

9 Power Supply Recommendations
CAUTION
Supply voltages larger than 44 V for a single supply, or outside the range of ±22 V for
a dual supply can permanently damage the device (see Absolute Maximum Ratings).
Place 0.1-µF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high
impedance power supplies. For more detailed information on bypass capacitor placement, see Layout.
10 Layout
10.1 Layout Guidelines
For best operational performance of the device, use quality PCB layout practices, including:
• Noise can propagate into analog circuitry through the power pins of the circuit as a whole, as well as the
operational amplifier. Bypass capacitors are used to reduce the coupled noise by providing low impedance
power sources local to the analog circuitry.
– Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as
close to the device as possible. A single bypass capacitor from V+ to ground is applicable for singlesupply applications.
• Separate grounding for analog and digital portions of circuitry is one of the simplest and most effective
methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes.
A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital
and analog grounds, paying attention to the flow of the ground current.
• Run the input traces as far away from the supply or output traces as possible to reduce parasitic coupling. If it
is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as opposed
to in parallel with the noisy trace.
• Place the external components as close to the device as possible. Keeping RF and RG close to the inverting
input minimizes parasitic capacitance, as shown in Layout Guidelines.
• Keep the length of input traces as short as possible. Always remember that the input traces are the most
sensitive part of the circuit.
• Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce
leakage currents from nearby traces that are at different potentials.
