The OPA234 series low-cost op amps are ideal for  
single-supply, low-voltage, low-power applications. The  
series provides lower quiescent current than older  
“1013”-type products and comes in current industry-  
standard packages and pinouts. The combination of  
low offset voltage, high common-mode rejection, high  
power-supply rejection, and a wide supply range pro-  
vides excellent accuracy and versatility. Single, dual,  
and quad versions have identical specifications for  
maximum design flexibility. These general-purpose op  
amps are ideal for portable and battery-powered appli-  
cations.

OPA4234  
The OPA234 series op amps operate from either single  
or dual supplies. In single-supply operation, the input  
common-mode range extends below ground and the  
output can swing to within 50mV of ground. Excellent  
phase margin makes the OPA234 series ideal for de-  
manding applications, including high load capacitance.  
Dual and quad designs feature completely indepen-  
dent circuitry for lowest crosstalk and freedom from  
interaction.

APPLICATIONS INFORMATION  
V+  
The OPA234 series op amps are unity-gain stable and  
suitable for a wide range of general-purpose applications.  
Power-supply pins should be bypassed with 10nF ceramic  
capacitors.  
10nF  
OPA234 single op amp only.  
Use offset adjust pins only to null  
offset voltage of op amp—see text.

10nF  
100kΩ  
The OPA234 series op amps operate from single (+2.7V to  
+36V) or dual (±1.35V to ±18V) supplies with excellent  
performance. Specifications are production tested with +2.7V,  
+5V, and ±15V supplies. Most behavior remains unchanged  
throughout the full operating voltage range. Parameters  
which vary significantly with operating voltage are shown in  
the Typical Characterisitc curves.  
Trim Range: ±4mV typ  
(V–) = 0V for single supply operation.

FIGURE 1. OPA234 Offset Voltage Trim Circuit.  
OFFSET VOLTAGE TRIM  
Offset voltage of the OPA234 series amplifiers is laser  
trimmed and usually requires no user adjustment. The  
OPA234 (single op amp version) provides offset voltage  
trim connections on pins 1 and 5. Offset voltage can be  
adjusted by connecting a potentiometer, as shown in Fig-  
ure 1. This adjustment should be used only to null the offset  
of the op amp, not to adjust system offset or offset pro-  
duced by the signal source. Nulling offset could degrade  
the offset drift behavior of the op amp. While it is not  
possible to predict the exact change in drift, the effect is  
usually small.

http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,  
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should  
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are  
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.  
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard  
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where  
mandated by government requirements, testing of all parameters of each product is not necessarily performed.  
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and  
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,  
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information  
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a  
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual  
property of the third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied  
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive  
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional  
restrictions.  
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all  
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not  
responsible or liable for any such statements.  
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably  
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing  
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and  
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products  
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be  
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in  
such safety-critical applications.  
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are  
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military  
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at  
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.  
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are  
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated  
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
