FEATURES
DESCRIPTION
● 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
● WIDE SUPPLY RANGE:
Single Supply: 2.2V to 36V
Dual Supply: ±1.1V to ±18V
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 performance 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 applications. 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.

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 degradation 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 degrade 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
This allows a designer to have the same assured performance 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. Parameters which vary significantly with operating voltage or
temperature are shown in typical performance curves.
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 SurfaceMount Devices,” easily found at Burr-Brown's web site
(http://www.burr-brown.com).
