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.

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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check 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)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
