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.

Single version packages are in an SO-8 surface-mount
and a space-saving MSOP-8 surface-mount. Dual pack-
ages are in an SO-8 surface-mount. Quad packages
are in an SO-14 surface-mount. All are specified for
–40°C to +85°C operation.

dling and installation procedures can cause damage.

may be more susceptible to damage because very small

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.

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.

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.

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)
