1µA, Rail-to-Rail I/O CMOS
OPERATIONAL AMPLIFIERS
DESCRIPTION
FEATURES
The OPA349 and OPA2349 are ultra-low power operational
amplifiers that provide 70kHz bandwidth with only 1µA quies-
cent 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 band-
width. 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.
APPLICATIONS
● BATTERY PACKS AND POWER SUPPLIES
● PORTABLE PHONES, PAGERS, AND CAMERAS
● SOLAR-POWERED SYSTEMS
● SMOKE, GAS, AND FIRE DETECTION SYSTEMS
● REMOTE SENSORS
● PCMCIA CARDS
● DRIVING ANALOG-TO-DIGITAL (A/D) CONVERTERS
● MicroPOWER FILTERS
The OPA349 comes in miniature SOT23-5, SC70, and SO-8
surface-mount packages. The OPA2349 dual is available in
SOT23-8, and SO-8 surface-mount packages. These tiny
packages are ideal for use in high-density applications, such
as PCMCIA cards, battery packs, and portable instruments.
The OPA349 is specified for 0°C to +70°C. The OPA2349 is
specified for –40°C to +70°C.

This integrated circuit can be damaged by ESD. Texas Instru-
ments 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. These are stress ratings only, and functional opera-
tion 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.

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 pro-
duce 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 quies-
cent current requirements.
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.
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
inparallelwithaP-channeldifferentialpair(asshowninFigure2).
TheN-channelpairisactiveforinputvoltagesclosetothepositive
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
transitionregion,typically(V+)–1.5Vto(V+)–1.1V,inwhichboth
pairs are on. This 400mV transition region can vary 300mV with
processvariation.Thus,thetransitionregion(bothstageson)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
THDmaybedegradedcomparedtooperationoutsidethisregion.
For more information on designing with rail-to-rail input op amps,
see Figure 3, Design Optimization with Rail-to-Rail Input Op
Amps.
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

DESIGN OPTIMIZATION WITH RAIL-TO-RAIL INPUT OP AMPS
In most applications, operation is within the range of only one
wide input swing is required. A design option would be to
configure the op amp as a unity-gain inverter as shown below
andholdthenoninvertinginputatasetcommon-modevoltage
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.
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 problem-

COMMON-MODE REJECTION
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 opera-
tion a few microseconds after the output is driven positively
out of the rail.
TheCMRRfortheOPA349is specifiedintwowayssothebest
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 applica-
tion requires use of one of the differential input pairs. Second,
the CMRR at VS = 5V over the entire common-mode range is
specified.
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 negative-
going 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.
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
