FEATURES
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.
● MicroSIZE PACKAGES
OPA244 (Single): SOT-23-5
OPA2244 (Dual): MSOP-8
OPA4244 (Quad): TSSOP-14
● MicroPOWER: IQ = 50µA/channel
● SINGLE SUPPLY OPERATION
● WIDE BANDWIDTH: 430kHz
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.
● WIDE SUPPLY RANGE:
Single Supply: 2.2V to 36V
Dual Supply: ±1.1V to ±18V
APPLICATIONS
● BATTERY POWERED SYSTEMS
● PORTABLE EQUIPMENT
● PCMCIA CARDS
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.

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 Capability ................................................................................ 2000V
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.

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.
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.
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).

(2) 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 <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(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 finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
