OPERATIONAL AMPLIFIER

DESCRIPTION

The OPA363 and OPA364 families are high-performance
CMOS operational amplifiers optimized for very low voltage,
single-supply operation. These miniature, low-cost amplifiers
are designed to operate on single supplies from 1.8V (±0.9V)
to 5.5V (±2.75V). Applications include sensor amplification
and signal conditioning in battery-powered systems.

The OPA363 and OPA364 families offer excellent CMRR
without the crossover associated with traditional complimen­tary input stages. This results in excellent performance for
driving Analog-to-Digital (A/D) converters without degrada­tion of differential linearity and THD. The input common­mode range includes both the negative and positive supplies.
The output voltage swing is within 10mV of the rails.

The OPA363 family includes a shutdown mode. Under logic
control, the amplifiers can be switched from normal operation
to a standby current that is less than 1µA.

The single version is available in the

Micro

SIZE SOT23-5
(SOT23-6 for shutdown) and SO-8. The dual version is
available in MSOP-8, MSOP-10, and SO-8 packages. Quad
packages are available in TSSOP-14 and SO-14 packages.
All versions are specified for operation from –40°C to +125°C.

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.

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

APPLICATIONS INFORMATION

The OPA363 and OPA364 series op amps are rail-to-rail
operational amplifiers with excellent CMRR, low noise, low
offset, and wide bandwidth on supply voltages as low as
±0.9V. The OPA363 features an additional pin for shutdown/
enable function. These families do not exhibit phase reversal
and are unity-gain stable. Specified over the industrial tem­perature range of –40°C to +125°C, the OPA363 and OPA364
families offer precision performance for a wide range of
applications.

RAIL-TO-RAIL INPUT

The OPA363 and OPA364 feature excellent rail-to-rail opera­tion, with supply voltages as low as ±0.9V. The input com­mon-mode voltage range of the OPA363 and OPA364 family
extends 100mV beyond supply rails. The unique input topol­ogy of the OPA363 and OPA364 eliminates the input offset
transition region typical of most rail-to-rail complimentary
stage operational amplifiers, allowing the OPA363 and
OPA364 to provide superior common-mode performance
over the entire common-mode input range, as seen in Figure 1.
This feature prevents degradation of the differential linearity
error and THD when driving A/D converters. A simplified
schematic of the OPA363 and OPA364 is shown in Figure 2.

OPERATING VOLTAGE

The OPA363 and OPA364 series op amp parameters are fully
specified from +1.8V to +5.5V. Single 0 .1µF bypass capaci­tors should be placed across supply pins and as close to the
part as possible. Supply voltages higher than 5.5V (absolute
maximum) may cause permanent damage to the amplifier.
Many specifications apply from –40°C to +125°C. Parameters
that vary significantly with operating voltages or temperature
are shown in the Typical Characteristics.

ENABLE FUNCTION

The shutdown (enable) function of the OPA363 is referenced
to the negative supply voltage of the operational amplifier. A
logic level HIGH enables the op amp. A valid logic HIGH is
defined as voltage > 75% of the positive supply applied to the
enable pin. The valid logic HIGH signal can be as much as

5.5V above the negative supply, independent of the positive
supply voltage. A valid logic LOW is defined as < 0.8V above
the negative supply pin. If dual or split power supplies are
used, care should be taken to ensure logic input signals are
properly referred to the negative supply voltage. This pin
should be connected to a valid high or low voltage or driven,
not left open circuit.

The logic input is a high-impedance CMOS input. Dual op
amps are provided separate logic inputs. For battery-oper­ated applications, this feature may be used to greatly reduce
the average current and extend battery life. The enable time
is 20µs; disable time is 1µs. When disabled, the output
assumes a high-impedance state. This allows the OPA363 to
be operated as a “gated” amplifier, or to have its output
multiplexed onto a common analog output bus.

The OPA363 and OPA364 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 determining stability. An op amp in unity-gain
configuration is the most susceptible to the effects of capaci­tive load. The capacitive load reacts with the output resis­tance of the op amp to create a pole in the small-signal
response, which degrades the phase margin.

In unity gain, the OPA363 and OPA364 series op amps
perform well with a pure capacitive load up to approximately
1000pF. The ESR (Equivalent Series Resistance) of the
loading capacitor may be sufficient to allow the OPA363 and
OPA364 to directly drive very large capacitive loads (> 1µF).
Increasing gain enhances the amplifier’s ability to drive more
capacitance. See the typical characteristic “Small-Signal Over­shoot vs Capacitive Load.”

One method of improving capacitive load drive in the unity­gain configuration is to insert a 10Ω to 20Ω resistor in series
with the output, as shown in Figure 3. 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 R

L

= 10kΩ and RS = 20Ω, there is

only about a 0.2% error at the output.

INPUT AND ESD PROTECTION

All OPA363 and OPA364 pins are static protected with
internal ESD protection diodes tied to the supplies. These
diodes will provide overdrive protection if the current is
externally limited to 10mA, as stated in the absolute maxi­mum ratings and shown in Figure 4.

ACHIEVING OUTPUT SWING TO
THE OP AMP’S NEGATIVE RAIL

Some applications require an accurate output voltage swing
from 0V to a positive full-scale voltage. A good single supply op
amp may be abl e to swing wi thin a few mV of single supply
ground, but as the output is driven toward 0V, the output stage
of the amplifier will prevent the output from reaching the
negative supply rail of the amplifier.

The output of the OPA363 or OPA364 can be made to swing to
ground, or slightly below, on a single supply power source. To do
so requires use of another resistor and an additional, more
negative power supply than the op amp’s negative supply. A
pulldown resistor may be connected between the output and the
additional negative supply to pull the output down below the value
that the output would otherwise achieve as shown in Figure 5.

OVERLOAD

This technique will not work with all op amps. The output
stage of the OPA363 and OPA364 allows the output voltage
to be pulled below that of most op amps, if approximately
500µA is maintained through the output stage. To calculate
the appropriate value load resistor and negative supply,
R

L

= –V/500µA. The OPA363 and OPA364 have been
characterized to perform well under the described conditions,
maintaining excellent accuracy down to 0V and as low as
–10mV. Limiting and nonlinearity occur below –10mV, with
linearity returning as the output is again driven above
–10mV.

BUFFERED REFERENCE VOLTAGE

Many single-supply applications require a mid-supply refer­ence voltage. The OPA363 and OPA364 offer excellent
capacitive load drive capability, and can be configured to
provide a 0.9V reference voltage, as can be seen in Figure 6.
For appropriate loading considerations, see the “Capacitive
Load” section.

AUDIO APPLICATIONS

The OPA363 and OPA364 op amp family has linear offset
voltage over the entire input common-mode range. Com­bined with low-noise, this feature makes the OPA363 and
OPA364 suitable for audio applications. Single supply 1.8V
operation allows the OPA2363 and OPA2364 to be optimal
candidates for dual stereo-headphone drivers and micro­phone pre-amplifiers in portable stereo equipment, see Fig­ures 9 and 10.

DIRECTLY DRIVING THE ADS8324 AND
THE MSP430

The OPA363 and OPA364 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 no crossover input stage of the
OPA363 and OPA364 directly drive A/D converters without
degradation of differential linearity and THD. They provide an
effective means of buffering the A/D converters input capaci­tance and resulting charge injection while providing signal
gain. Figure 7 and Figure 8 show the OPA363 and OPA364
configured to drive the ADS8324 and the 12-bit
A/D converter on the MSP430.

ACTIVE FILTERING

Low harmonic distortion and noise specifications plus high
gain and slew rate make the OPA363 and OPA364 optimal
candidates for active filtering. Figure 11 shows the OPA2363
configured as a low-distortion, 3rd-order GIC (General Immit­tance Converter) filter. Figure 12 shows the implementation
of a Sallen-Key, 3-pole, low-pass Bessel filter.
