LMV34x Rail-to-Rail Output CMOS Operational Amplifiers
With Shutdown
1 Features

•
•
•
•
•
•
The LMV34x devices are single, dual, and quad
CMOS operational amplifiers, respectively, with low
voltage, low power, and rail-to-rail output swing
capabilities. The PMOS input stage offers an ultra-low
input bias current of 1 pA (typical) and an offset
voltage of 0.25 mV (typical). The single-supply
amplifier is designed specifically for low-voltage
(2.7 V to 5 V) operation, with a wide common-mode
input voltage range that typically extends from –0.2 V
to 0.8 V from the positive supply rail. The LMV341
(single) also offers a shutdown (SHDN) pin that can
be used to disable the device. In shutdown mode, the
supply current is reduced to 33 nA (typical).
Additional features of the family are a 20-nV/√Hz
voltage noise at 10 kHz, 1-MHz unity-gain bandwidth,
1-V/μs slew rate, and 100-μA current consumption
per channel.

Offered in both the SOT-23 and smaller SC70
packages, the LMV341 is suitable for the most spaceconstraint applications. The LMV342 dual device is
offered in the standard SOIC and VSSOP packages.
An extended industrial temperature range from –40°C
to 125°C makes these devices suitable in a wide
variety of commercial and industrial environments.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values (except differential voltages) are with respect to the network GND.
Differential voltages are at IN+ with respect to IN−.

For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application
report, SPRA953.
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.
The package thermal impedance is calculated in accordance with JESD 51-7.

7 Detailed Description
7.1 Overview
The LMV34x devices are precision operational amplifiers with CMOS inputs for very low input bias current.
Output is rail-to-rail and input common-mode includes ground. LMV341 has a shutdown mode for very low supply
current.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 PMOS Input Stage
PMOS Input Stage supports a lower input range that includes ground. Upper range limit is V+ – 1 V.
7.3.2 CMOS Output Stage
The CMOS drain output topology allows rail-to-rail output swing.
7.3.3 Shutdown
LMV341 includes a shutdown pin. During shutdown, ICC is nearly zero and the output becomes high impedance.
The typical turnon time coming out of shutdown is 5 µs.
7.4 Device Functional Modes
The LMV34x devices have two modes of operation:
• Normal operation when SHDN pin is at V+ level or the SHDN pin is not present
• Shutdown mode when SHDN is at GND level; ICC is very low and output is high impedance.

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
LMV34x devices have rail-to-rail output and input range from ground to VCC – 1 V. CMOS inputs provide very
low input current. Shutdown capability is an option in dual amplifier version. Operation from 2.5-V to 5.5-V is
possible.
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.
RF
RI
Vsup+
VOUT
+
VIN
VsupCopyright © 2016, Texas Instruments Incorporated
Figure 37. 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 ± 2 V is sufficient to
accommodate this application. The supplies can power up in any order; however, neither supply can be of
opposite polarity relative to ground at any time; otherwise, a large current can flow though the input ESD diodes.
To limit current in such an occurrence, TI highly recommends adding a series resistor to the grounded input.
Vsup+ must be more positive than Vsup– at all times; otherwise, a large reverse supply current may flow.
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 uses currents in the mA range. This ensures the part does not draw too much
current. For this example, choose 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 5.5 V for a single supply can permanently damage the
device (see the Absolute Maximum Ratings).
Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or highimpedance power supplies.

10 Layout
10.1 Layout Guidelines
For best operational performance of the device, use good 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 single-supply
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, and pay attention to the flow of the ground current.
• To reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. 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 Examples.
• 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.

11.4 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
