●
The OPA349 and OPA2349 are ultra-low power operational
amplifiers that provide 70kHz bandwidth with only 1µA quiescent current. These rail-to-rail input and output amplifiers are
specifically designed for battery-powered applications. The
input common-mode voltage range extends 200mV beyond
the power-supply rails and the output swings to within 350mV
of the rails, maintaining wide dynamic range. Unlike some
micropower op amps, these parts are unity-gain stable and
require no external compensation to achieve wide bandwidth. The OPA349 features a low input bias current that
allows the use of large source and feedback resistors.
LOW SUPPLY CURRENT: 1µA
GAIN-BANDWIDTH: 70kHz
UNITY-GAIN STABLE
LOW INPUT BIAS CURRENT: 10pA (max)
WIDE SUPPLY RANGE: 1.8V to 5.5V
INPUT RANGE: 200mV Beyond Rails
OUTPUT SWINGS TO 350mV OF RAILS
OUTPUT DRIVE CURRENT: 8mA
OPEN-LOOP GAIN: 90dB
MicroPACKAGES: SC70, SOT23-5, SOT23-8
The OPA349 can be operated with power supplies from 1.8V
to 5.5V with little change in performance, ensuring continuing
superior performance even in low battery situations.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these, or any other conditions beyond those specified,
is not implied. (2) Input terminals are diode-clamped to the power-supply
rails. Input signals that can swing more than 0.5V beyond the supply rails
should be current-limited to 10mA or less. (3) Short-circuit to ground, one
amplifier per package.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments 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.

APPLICATIONS INFORMATION
The OPA349 series op amps are unity-gain stable and can
operate on a single supply, making them highly versatile and
easy to use. Power-supply pins should be bypassed with
0.01µF ceramic capacitors.
The OPA349 series op amps are fully specified and tested
from +1.8V to +5.5V. Parameters that vary significantly with
operating voltages or temperature are shown in the Typical
Characteristic curves.
The ultra-low quiescent current of the OPA349 requires
careful application circuit techniques to achieve low overall
current consumption. Figure 1 shows an ac-coupled amplifier
+1.8V to 5.5V

biased with a voltage divider. Resistor values must be very
large to minimize current. The large feedback resistor value
reacts with input capacitance and stray capacitance to produce a pole in the feedback network. A feedback capacitor
may be required to assure stability and limit overshoot or
gain peaking. Check circuit performance carefully to assure
that biasing and feedback techniques meet signal and quiescent current requirements.
RAIL-TO-RAIL INPUT
The input common-mode voltage range of the OPA349 series
extends 200mV beyond the supply rails. This is achieved with a
complementary input stage—an N-channel input differential pair
in parallel with a P-channel differential pair (as shown in Figure 2).
The N-channel pair is active for input voltages close to the positive
rail, typically (V+) – 1.3V to 200mV above the positive supply,
while the P-channel pair is on for inputs from 200mV below the
negative supply to approximately (V+) – 1.3V. There is a small
transition region, typically (V+) – 1.5V to (V+) – 1.1V, in which both
pairs are on. This 400mV transition region can vary 300mV with
process variation. Thus, the transition region (both stages on) can
range from (V+) – 1.8V to (V+) – 1.4V on the low end, up to
(V+) – 1.2V to (V+) – 0.8V on the high end. Within the 400mV
transition region PSRR, CMRR, offset voltage, offset drift, and
THD may be degraded compared to operation outside this region.

DESIGN OPTIMIZATION WITH RAIL-TO-RAIL INPUT OP AMPS
wide input swing is required. A design option would be to
configure the op amp as a unity-gain inverter as shown below
and hold the noninverting input at a set common-mode voltage
outside the transition region. This can be accomplished with a
voltage divider from the supply. The voltage divider should be
designed such that the biasing point for the noninverting input
is outside the transition region.
In most applications, operation is within the range of only one
differential pair. However, some applications can subject the
amplifier to a common-mode signal in the transition region.
Under this condition, the inherent mismatch between the two
differential pairs may lead to degradation of the CMRR and
THD. The unity-gain buffer configuration is the most problematic—it will traverse through the transition region if a sufficiently

COMMON-MODE REJECTION
The CMRR for the OPA349 is specified in two ways so the best
match for a given application may be used. First, the CMRR of
the device in the common-mode range below the transition
region (VCM < (V+) – 1.5V) is given. This specification is the
best indicator of the capability of the device when the application requires use of one of the differential input pairs. Second,
the CMRR at VS = 5V over the entire common-mode range is
specified.
OUTPUT DRIVEN TO V– RAIL
Loads that connect to single-supply ground (or the V– supply
pin) can cause the OPA349 or OPA2349 to oscillate if the
output voltage is driven into the negative rail (as shown in
a)
Figure 4a). Similarly, loads that can cause current to flow out
of the output pin when the output voltage is near V– can
cause oscillations. The op amp will recover to normal operation a few microseconds after the output is driven positively
out of the rail.
Some op amp applications can produce this condition even
without a load connected to V–. The integrator in Figure 4b
shows an example of this effect. Assume that the output
ramps negatively, and saturates near 0V. Any negativegoing step at VIN will produce a positive output current pulse
through R1 and C1. This may incite the oscillation. Diode D1
prevents the input step from pulling output current when the
output is saturated at the rail, thus preventing the oscillation.

accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
