DESCRIPTION
The OPA244 (single), OPA2244 (dual), and OPA4244 (quad)
op amps are designed for very low quiescent current
(50µA/channel), yet achieve excellent bandwidth. Ideal for
battery powered and portable instrumentation, all versions are
offered in micro packages for space-limited applications.
The dual and quad versions feature completely independent
circuitry for lowest crosstalk and freedom from interaction, even
when overdriven or overloaded.
The OPA244 series is easy to use and free from phase
inversion and overload problems found in some other op amps.
These amplifiers are stable in unity gain and excellent perfor-
mance is maintained as they swing to their specified limits.
They can be operated from single (+2.2V to +36V) or dual
supplies (±1.1V to ±18V). The input common-mode voltage
range includes ground—ideal for many single supply applica-
tions. All versions have similar performance. However, there
are some differences, such as common-mode rejection. All
versions are interchangeable in most applications.
All versions are offered in miniature, surface-mount packages.
OPA244 (single version) comes in the tiny 5-lead SOT-23-5
surface mount, SO-8 surface mount, and 8-pin DIP. OPA2244
(dual version) is available in the MSOP-8 surface mount,
SO-8 surface-mount, and 8-pin DIP. The OPA4244 (quad)
comes in the TSSOP-14 surface mount. They are fully specified
from –40°C to +85°C and operate from –55°C to +125°C.
A SPICE Macromodel is available for design analysis.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
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 degrada-
tion 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.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may de-
grade device reliability. (2) Inputs are diode-clamped to the supply rails and
should be current-limited to 10mA or less if input voltages can exceed rails
by more than 0.3V. (3) Short-circuit to ground, one amplifier per package.

APPLICATIONS INFORMATION
The OPA244 is unity-gain stable and suitable for a wide
range of general purpose applications. Power supply pins
should be bypassed with 0.01µF ceramic capacitors.
OPERATING VOLTAGE
The OPA244 can operate from single supply (+2.2V to
+36V) or dual supplies (±1.1 to ±18V) with excellent
performance. Unlike most op amps which are specified at
only one supply voltage, the OPA244 is specified for real
world applications; a single set of specifications applies
throughout the +2.6V to +36V (±1.3 to ±18V) supply range.
This allows a designer to have the same assured perfor-
mance at any supply voltage within this range. In addition,
many key parameters are guaranteed over the specified
temperature range, –40°C to +85°C. Most behavior remains
unchanged throughout the full operating voltage range. Pa-
rameters which vary significantly with operating voltage or
temperature are shown in typical performance curves.
Useful information on solder pad design for printed circuit
boards can be found in Burr-Brown's Application Bulletin
AB-132B, “Solder Pad Recommendations for Surface-
Mount Devices,” easily found at Burr-Brown's web site
(http://www.burr-brown.com).

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
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 which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
