DESCRIPTION
The OPA349 and the OPA2349 are ultra-low power opera-
tional amplifiers that provide 70kHz bandwidth with only 1
A
quiescent current. These rail-to-rail input and output amplifi-
ers are specifically designed for battery-powered applica-
tions. The input common-mode voltage range extends 200mV
beyond the power supply rails and the output swings to within
150mV 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.
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.
OPA349 comes in the miniature SOT23-5, SC70, and SO-8
surface mount packages. OPA2349 dual is available in the
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 40
C to +125
C. The OPA2349
is specified for 40
C to +70
C.

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.

DISCHARGE SENSITIVITY
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.

APPLICATIONS INFORMATION
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 0.01
F
ceramic capacitors.
OPA349 series op amps are fully specified and tested from
+1.8V to +5.5V. Parameters that vary significantly with operat-
ing voltages or temperature are shown in the Typical Charac-
teristics Curves.
The ultra low quiescent current of the OPA349 requires
careful applications circuit techniques to achieve low overall
current consumption. Figure 1 shows an ac-coupled amplifier
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 your 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. For more informa-
tion on designing with rail-to-rail input op amps, see Figure 3
"Design Optimization with Rail-to-Rail Input Op Amps."

FIGURE 3. Design Optimization.
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 problem-
atic--it will traverse through the transition region if a sufficiently
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.
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 (V
CM
< (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 V
S
= 5V over the entire common-mode range is
specified.
OUTPUT DRIVEN TO V RAIL (DUAL VERSION ONLY)
Loads that connect to single-supply ground (or the V- supply
pin) can cause the OPA2349 (dual version) to oscillate if the
output voltage is driven into the negative rail (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. Assume that the output ramps nega-
tively, and saturates near 0V. Any negative-going step at V
IN
will produce a positive output current pulse through R
1
and
C
1
. This may incite the oscillation. Diode, D
1
, prevents the
input step from pulling output current when the output is
saturated at the rail, thus preventing the oscillation.
