of the supply rails with a 100kΩ load. They offer excel-
lent dynamic response (BW = 5.5MHz, SR = 6V/µs), yet
quiescent current is only 750µA. Dual and quad designs
feature completely independent circuitry for lowest
crosstalk and freedom from interaction.
DESCRIPTION
OPA340 series rail-to-rail CMOS operational amplifi-
ers are optimized for low voltage, single supply opera-
tion. Rail-to-rail input/output and high speed operation
make them ideal for driving sampling analog-to-digital
converters. They are also well suited for general pur-
pose and audio applications as well as providing I/V
conversion at the output of D/A converters. Single,
dual, and quad versions have identical specifications
for design flexibility.
The single (OPA340) packages are the tiny 5-lead
SOT-23-5 surface mount, SO-8 surface mount, and
8-pin DIP. The dual (OPA2340) comes in the minia-
ture MSOP-8 surface mount, SO-8 surface mount,
and 8-pin DIP packages. The quad (OPA4340) pack-
ages are the space-saving SSOP-16 surface mount,
SO-14 surface mount, and the 14-pin DIP. All are
specified from –40°C to +85°C and operate from
–55°C to +125°C. A SPICE macromodel is available
for design analysis.
The OPA340 series operates on a single supply as low as
2.5V with an input common-mode voltage range that
extends 500mV below ground and 500mV above the
positive supply. Output voltage swing is to within 1mV

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

APPLICATIONS INFORMATION
OPA340 series op amps are fabricated on a state-of-the-art
0.6 micron CMOS process. They are unity-gain stable and
suitable for a wide range of general purpose applications.
Rail-to-rail input/output make them ideal for driving sam-
pling A/D converters. In addition, excellent ac performance
makes them well-suited for audio applications. The class AB
output stage is capable of driving 600Ω loads connected to
any point between V+ and ground.
OPERATING VOLTAGE
OPA340 series op amps are fully specified from +2.7V to
+5V. However, supply voltage may range from +2.5V to
+5.5V. Parameters are guaranteed over the specified supply
range—a unique feature of the OPA340 series. In addition,
many specifications apply from –40°C to +85°C. Most
behavior remains virtually unchanged throughout the full
operating voltage range. Parameters which vary signifi-
cantly with operating voltages or temperature are shown in
the typical performance curves.
Rail-to-rail input and output swing significantly increases
dynamic range, especially in low supply applications.
Figure 1 shows the input and output waveforms for the
OPA340 in unity-gain configuration. Operation is from a
single +5V supply with a 10kΩ load connected to VS /2.
The input is a 5Vp-p sinusoid. Output voltage is approxi-
mately 4.98Vp-p.
RAIL-TO-RAIL INPUT
The input common-mode voltage range of the OPA340
series extends 500mV beyond the supply rails. This is
achieved with a complementary input stage—an N-channel
input differential pair in parallel with a P-channel differen-
tial pair (see Figure 2). The N-channel pair is active for input
voltages close to the positive rail, typically
(V+) –1.3V to 500mV above the positive supply, while the
P-channel pair is on for inputs from 500mV 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 transi-
tion 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.

OPA340 series op amps are laser-trimmed to the reduce
offset voltage difference between the N-channel and
P-channel input stages, resulting in improved common-
mode rejection and a smooth transition between the
N-channel pair and the P-channel pair. However, within the
400mV transition region PSRR, CMRR, offset voltage,
offset drift, and THD may be degraded compared to opera-
tion outside this region.
CAPACITIVE LOAD AND STABILITY
OPA340 series op amps can drive a wide range of capacitive
loads. However, all op amps under certain conditions may
become unstable. Op amp configuration, gain, and load
value are just a few of the factors to consider when determin-
ing stability. An op amp in unity gain configuration is the
most susceptible to the effects of capacitive load. The
capacitive load reacts with the op amp’s output resistance,
along with any additional load resistance, to create a pole in
the small-signal response which degrades the phase margin.
In unity gain, OPA340 series op amps perform well, with a
pure capacitive load up to approximately 1000pF. Increasing
gain enhances the amplifier’s ability to drive more capaci-
tance. See the typical performance curve “Small-Signal
Overshoot vs Capacitive Load.”
A double-folded cascode adds the signal from the two input
pairs and presents a differential signal to the class AB output
stage. Normally, input bias current is approximately 200fA,
however, input voltages exceeding the power supplies by
more than 500mV can cause excessive current to flow in or
out of the input pins. Momentary voltages greater than
500mV beyond the power supply can be tolerated if the
current on the input pins is limited to 10mA. This is easily
accomplished with an input resistor as shown in Figure 3.
Many input signals are inherently current-limited to less
than 10mA, therefore, a limiting resistor is not required.
One method of improving capacitive load drive in the unity
gain configuration is to insert a 10Ω to 20Ω resistor in series
with the output, as shown in Figure 4. This significantly
reduces ringing with large capacitive loads. However, if
there is a resistive load in parallel with the capacitive load,
it creates a voltage divider introducing a dc error at the
output and slightly reduces output swing. This error may be
insignificant. For instance, with RL = 10kΩ and RS = 20Ω,
there is only about a 0.2% error at the output.

DRIVING A/D CONVERTERS
VIN
OPA340 series op amps are optimized for driving medium
speed (up to 100kHz) sampling A/D converters. However,
they also offer excellent performance for higher speed
converters. The OPA340 series provides an effective means
of buffering the A/D’s input capacitance and resulting
charge injection while providing signal gain.

the Supply Voltage.
Figures 5 and 6 show the OPA340 driving an ADS7816.
The ADS7816 is a 12-bit, micro-power sampling converter
in the tiny MSOP-8 package. When used with the minia-
ture package options of the OPA340 series, the combina-
tion is ideal for space-limited and low power applications.
For further information consult the ADS7816 data sheet.
RAIL-TO-RAIL OUTPUT
A class AB output stage with common-source transistors is
used to achieve rail-to-rail output. For light resistive loads
(>50kΩ), the output voltage is typically a few millivolts
from the supply rails. With moderate resistive loads (2kΩ to
50kΩ), the output can swing to within a few tens of milli-
volts from the supply rails and maintain high open-loop
gain. See the typical performanc curve “Output Voltage
Swing vs Output Current.”
With the OPA340 in a noninverting configuration, an RC
network at the amplifier’s output can be used to filter high
frequency noise in the signal (Figure 5). In the inverting
configuration, filtering may be accomplished with a ca-
pacitor across the feedback resistor (Figure 6).
