A low supply current of 45 µA and an input bias
current of 0.5 pA, makes the OPAx348 series an
optimal candidate for low-power applications such as
smoke detectors and other high-impedance sensors.
The OPA348 is available in the miniature 5-pin SC70
(SOT), 5-pin SOT-23 (SOT), and 8-pin SO (SOIC)
packages. The OPA2348 is available in 8-pin SOT-23
(SOT) and 8-pin SO (SOIC) packages, and the
OPA4348 is offered in space-saving 14-pin TSSOP
and 14-pin SO (SOIC) packages. The extended
temperature range of –40°C to +125°C over all
supply voltages offers design flexibility.

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. Functional operation of the device at these conditions, or beyond the specified
operating conditions, is not implied.
Input terminals are not diode-clamped to the power-supply rails. Input signals that can swing more than 0.5 V beyond the supply rails
must be current-limited to 10 mA or less.

7.3.1 Operating Voltage
The OPAx348 series op amps are fully specified and tested from 2.5 V to 5.5 V. However, supply voltage may
range from 2.1 V to 5.5 V. Parameters are tested over the specified supply range which is an unique feature of
the OPAx348 series. All temperature specifications apply from –40°C to +125°C. Most behavior remains virtually
unchanged throughout the full operating voltage range. Parameters that vary significantly with operating voltages
or temperature are shown in the Typical Characteristics section.

Feature Description (continued)
7.3.2 Common-Mode Voltage Range
The input common-mode voltage range of the OPA348 series extends 200 mV beyond the supply rails. This
extended range is achieved with a complementary input stage which is a N-channel input differential pair in
parallel with a P-channel differential pair. The N-channel pair is active for input voltages close to the positive rail,
typically (V+) – 1.2 V to 300 mV above the positive supply, while the P-channel pair is on for inputs from 300 mV
below the negative supply to approximately (V+) – 1.4 V. There is a small transition region, typically (V+) – 1.4 V
to (V+) – 1.2 V, in which both pairs are on. This 200-mV transition region, shown in Figure 19, can vary ±300 mV
with process variation. Thus, the transition region (both stages on) ranges from (V+) – 1.7 V to (V+) – 1.5 V on
the low end, up to (V+) – 1.1 V to (V+) – 0.9 V on the high end. Within the 200-mV transition region PSRR,
CMRR, offset voltage, offset drift, and THD may be degraded compared to operation outside this region.

7.3.3 Rail-To-Rail Input
The input common-mode range extends from (V–) – 0.2 V to (V+) + 0.2 V. For normal operation, inputs must be
limited to this range. The absolute maximum input voltage is 500 mV beyond the supplies. Inputs greater than
the input common-mode range but less than the maximum input voltage, while not valid, do not cause any
damage to the op amp. Unlike some other op amps, if input current is limited the inputs may go beyond the
power supplies without phase inversion; see Figure 20.

Feature Description (continued)
Normally, input currents are 0.5 pA. However, large inputs (greater than 500 mV beyond the supply rails) can
cause excessive current to flow in or out of the input pins. Therefore, as well as keeping the input voltage below
the maximum rating, it is also important to limit the input current to less than 10 mA. This limiting is easily
accomplished with an input voltage resistor, as shown in Figure 21.

7.3.4 Rail-To-Rail Output
A class AB output stage with common-source transistors is used to achieve rail-to-rail output. This output stage is
capable of driving 5-kΩ loads connected to any potential between V+ and ground. For light resistive loads
(> 100 kΩ), the output voltage can typically swing to within 18 mV from supply rail. With moderately resistive
loads (10 kΩ to 50 kΩ), the output voltage can typically swing to within 100 mV of the supply rails while
maintaining high open-loop gain (see Figure 6).
7.3.5 Capacitive Load and Stability
The OPA348 in a unity-gain configuration can directly drive up to 250 pF pure capacitive load. Increasing the
gain enhances the ability of the amplifier to drive greater capacitive loads (see Figure 13). In unity-gain
configurations, capacitive load drive can be improved by inserting a small (10-Ω to 20-Ω) resistor, RS, in series
with the output, as shown in Figure 22. This small resistor significantly reduces ringing while maintaining dc
performance for purely capacitive loads. However, if there is a resistive load in parallel with the capacitive load, a
voltage divider is created, introducing a direct current (dc) error at the output and slightly reducing the output
swing. The error introduced is proportional to the ratio RS / RL, and is generally negligible.

Feature Description (continued)
In unity-gain inverter configuration, phase margin can be reduced by the reaction between the capacitance at the
op amp input, and the gain setting resistors, thus degrading capacitive load drive. Best performance is achieved
by using small valued resistors. For example, when driving a 500-pF load, reducing the resistor values from
100 kΩ to 5 kΩ decreases overshoot from 55% to 13% (see Figure 13). However, when large valued resistors
cannot be avoided, a small (4-pF to 6-pF) capacitor, CFB, can be inserted in the feedback, as shown in Figure 23.
This configuration significantly reduces overshoot by compensating the effect of capacitance, CIN, which includes
the amplifier input capacitance and printed circuit board (PCB) parasitic capacitance.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The OPA348 amplifier is a single-supply, CMOS op amp with 1-MHz unity-gain bandwidth and supply current of
only 45 µA. Its performance is optimized for a lower power (2.1 V to 5.5 V), single-supply application, with its
input common-mode voltage linear range extending 200 mV beyond the rails and the output voltage swing within
25 mV of either rail.
The OPA348 series features wide bandwidth and unity-gain stability with rail-to-rail input and output for increased
dynamic range. Figure 24 shows the input and output waveforms for the OPA348 in unity-gain configuration.
Operation is from a single 5-V supply with a 100-kΩ load connected to VS / 2. The input is a 5-VPP sinusoid.
Output voltage is approximately 4.98 VPP.
Power-supply pins must be bypassed with 0.01-µF ceramic capacitors.

8.1.1 Driving A/D Converters
The OPA348 series op amps are optimized for driving medium-speed sampling analog-to-digital converters
(ADCs). The OPA348 op amps buffer the ADC input capacitance and resulting charge injection while providing
signal gain.
Figure 25 shows the OPA348 in a basic noninverting configuration driving the ADS7822. The ADS7822 is a
12-bit, microPOWER sampling converter in the MSOP-8 package. When used with the low-power, miniature
packages of the OPA348, the combination is ideal for space-limited, low-power applications. In this configuration,
an RC network at the ADC input can be used to provide both an anti-aliasing filter and charge injection current.

8.2.1 Design Requirements
When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often required.
The simplest way to establish this limited bandwidth is to place an RC filter at the noninverting terminal of the
amplifier, as shown in Figure 27. If a steeper attenuation level is required, a two-pole or higher-order filter may be
used.
8.2.2 Detailed Design Procedure
The design goals for this circuit include these parameters:
• A noninverting gain of 10 V/V (20 dB)
• Design a single-pole response circuit with –3-dB roll-off at 15.9 kHz and 159 Hz
• Modify the design to increase attenuation level to –40-dB/decade (Sallen-Key Filter)
Use these design values:
• C1 = 0 nF, 10 nF, 1 µF
• R1 = 1 kΩ
• RG = 10 kΩ
• RF = 90 kΩ

Typical Application (continued)
Figure 28 shows how the output voltage of OPA348 changes over frequency depending on the value of C1 with a
constant R1 of 1 kΩ. Without any filtering of the input signal (C1 = 0), the –3-dB effective bandwidth is a function
of the OPA348 unity-gain bandwidth and closed-loop gain, f(–3dB) = UGBW/ACL, where ACL is closed-loop gain
and UGBW denotes unity-gain bandwidth. Thus, for a closed-loop gain = 10, f(–3dB) = 1 MHz/10 =100 kHz; refer
to Figure 28.
To further limit the output bandwidth, an appropriate choice of C1 must be made: for C1 = 10 nF,
1
1
=
fC =
2p ´ R1C1 2p ´ 13 ´ 1-8 = 15.9 kHz.

If even more attenuation is required, a multiple pole filter is required. The Sallen-Key filter may be used for this
task, as shown in Figure 29. For best results, the amplifier must have effective bandwidth that is at least 10 times
higher than the filter cutoff frequency. Failure to follow this guideline results in a phase shift of the amplifier,
which in turn leads to lower precision of the filter bandwidth. Additionally, in order to minimize the loading effect
between multiple RC pairs on overall the filter cutoff frequency, choose R = 10 × R1 and C2 = C1/10; see
Figure 29.

9 Power Supply Recommendations
The OPAx348 is specified for operation from 2.1 V to 5.5 V (±1.05 V to ±2.75 V); many specifications apply from
–40°C to +125°C. Parameters that can exhibit significant variance with regard to operating voltage or
temperature are presented in the Typical Characteristics.
CAUTION
Supply voltages larger than 5.5 V can permanently damage the device (see the
Absolute Maximum Ratings table).
Place 0.1-µF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high
impedance power supplies. For more detailed information on bypass capacitor placement, see Layout.
10 Layout
10.1 Layout Guidelines
For best operational performance of the device, use good PCB layout practices, including:
• Connect low equivalent series resistance (ESR), 0.1-µF ceramic bypass capacitors between each supply pin
and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is
applicable for single-supply applications.
– Noise can propagate into analog circuitry through the power pins of the circuit as a whole and op amp
itself. Bypass capacitors are used to reduce the coupled noise by providing low-impedance power sources
local to the analog circuitry.
• Make sure to physically separate digital and analog grounds paying attention to the flow of the ground
current. Separate grounding for analog and digital portions of circuitry is one of the simplest and mosteffective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to
ground planes. A ground plane helps distribute heat and reduces EMI noise pickup.
• In order to reduce parasitic coupling, run the input traces as far away from the supply or output traces as
possible. If these traces cannot be kept separate, crossing the sensitive trace perpendicular is much better as
opposed to in parallel with the noisy trace.
• Place the external components as close to the device as possible. As shown in Figure 31, keeping RF and
RG close to the inverting input minimizes parasitic capacitance.
• Keep the length of input traces as short as possible. Always remember that the input traces are the most
sensitive part of the circuit.
• Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce
leakage currents from nearby traces that are at different potentials.
• Clean the PCB following board assembly for best performance.
• Any precision integrated circuit may experience performance shifts due to moisture ingress into the plastic
package. After any aqueous PCB cleaning process, bake the PCB assembly to remove moisture introduced

11.8 Electrostatic Discharge Caution
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.
