3 Description
The OPAx322-Q1 series consists of single-, dual-,
and quad-channel CMOS operational amplifiers
featuring low noise and rail-to-rail inputs and outputs
optimized for low-power, single-supply applications.
Specified over a wide supply range from 1.8 V to 5.5
V, the low quiescent current of only 1.5 mA per
channel makes these devices well-suited for powersensitive applications.

8 Detailed Description
8.1 Overview
The OPAx322-Q1 family of operational amplifiers (op amps) are high-speed precision amplifiers well-suited to
drive 12-, 14-, and 16-bit analog-to-digital converters. Low-output impedance with flat frequency characteristics
and zero-crossover distortion circuitry enable high linearity over the full input common-mode range, achieving
true rail-to-rail input from a 1.8-V to 5.5-V single-supply.

8.3 Feature Description
8.3.1 Operating Voltage
The OPAx322-Q1 series op amps are unity-gain stable and can operate on a single-supply voltage (1.8 V to 5.5
V), or a split-supply voltage (±0.9 V to ±2.75 V), which makes the op amps highly versatile and easy to use. The
power-supply pins must have local bypass ceramic capacitors (typically 0.001 μF to 0.1 μF). These amplifiers are
fully specified from 1.8 V to 5.5 V and over the extended temperature range from –40°C to +125°C. Parameters
that can exhibit variance with regard to operating voltage or temperature are presented in Typical Characteristics.
8.3.2 Input and ESD Protection
The OPAx322-Q1 incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case of
input and output pins, this protection primarily consists of current-steering diodes connected between the input
and power-supply pins. These ESD protection diodes also provide in-circuit input overdrive protection, as long as
the current is limited to 10 mA as stated in Absolute Maximum Ratings. Many input signals are inherently currentlimited to less than 10 mA; therefore, a limiting resistor is not required. Figure 26 shows how a series input
resistor (RS) may be added to the driven input to limit the input current. The added resistor contributes thermal
noise at the amplifier input and the value must be kept to the minimum in noise-sensitive applications.

8.3.3 Phase Reversal
The OPAx322-Q1 family of op amps are designed to be immune to phase reversal when the input pins exceed
the supply voltages, which provides further in-system stability and predictability. Figure 27 shows the input
voltage exceeding the supply voltage without any phase reversal.

8.3.4 Feedback Capacitor Improves Response
For optimum settling time and stability with high-impedance feedback networks, it may be necessary to add a
feedback capacitor across the feedback resistor (RF), as shown in Figure 28. This capacitor compensates for the
zero created by the feedback network impedance and the OPAx322-Q1 input capacitance (and any parasitic
layout capacitance). The effect becomes more significant with higher impedance networks.

Feature Description (continued)
For the circuit shown in Figure 28, the value of the variable feedback capacitor must be selected so that the input
resistance times the input capacitance of the OPAx322-Q1 (typically 9 pF) plus the estimated parasitic layout
capacitance equals the feedback capacitor times the feedback resistor with Equation 1.
RIN × CIN = RF × CF
where
•
CIN is equal to the OPAx322-Q1 input capacitance (sum of differential and common-mode) plus the layout

(1)
The capacitor value can be adjusted until optimum performance is obtained.
8.3.5 EMI Susceptibility and Input Filtering
Operational amplifiers vary in susceptibility to electromagnetic interference (EMI). If conducted EMI enters the
device, the DC offset observed at the amplifier output may shift from the nominal value while EMI is present. This
shift is a result of signal rectification associated with the internal semiconductor junctions. While all operational
amplifier pin functions can be affected by EMI, the input pins are likely to be the most susceptible. The OPAx322Q1 operational amplifier family incorporates an internal input low-pass filter that reduces the amplifier response
to EMI. Both common-mode and differential mode filtering are provided by the input filter. The filter is designed
for a cutoff frequency of approximately 580 MHz (–3 dB), with a roll-off of 20 dB per decade.
8.3.6 Output Impedance
The open-loop output impedance of the OPAx322-Q1 common-source output stage is approximately 90 Ω. When
the op amp is connected with feedback, the loop gain significantly reduces this value. For each decade rise in
the closed-loop gain, the loop gain is reduced by the same amount, which results in a tenfold increase in
effective output impedance. While the OPAx322-Q1 output impedance remains flat over a wide frequency range.
At higher frequencies the output impedance rises as the open-loop gain of the op amp drops. However, at these
frequencies the output becomes capacitive as a result of parasitic capacitance. This characteristic prevents the
output impedance from becoming too high, which can cause stability problems when driving large capacitive
loads. As mentioned previously, the OPAx322-Q1 has excellent capacitive load drive capability for an op amp
with a bandwidth of this value.
8.3.7 Capacitive Load and Stability
The OPAx322-Q1 is designed to be used in applications where driving a capacitive load is required. As with all
op amps, there may be specific instances where the OPAx322-Q1 can become unstable. The particular op amp
circuit configuration, layout, gain, and output loading are some of the factors to consider when establishing
whether an amplifier is stable in operation. An op amp in the unity-gain (1-V/V) buffer configuration and driving a
capacitive load exhibits a greater tendency to become unstable than an amplifier operating at a higher noise
gain. The capacitive load, in conjunction with the op amp output resistance, creates a pole within the feedback
loop that degrades the phase margin.
The equivalent series resistance (ESR) of some very large capacitors (CL > 1 µF) is sufficient to alter the phase
characteristics in the feedback loop so the amplifier remains stable. Increasing the amplifier closed-loop gain
allows the amplifier to drive increasingly larger capacitance. This increased capability is evident when observing
the overshoot response of the amplifier at higher voltage gains, as shown in Figure 29. One technique for
increasing the capacitive load drive capability of the amplifier operating in unity gain is to insert a small resistor
(RS, typically 10-Ω to 20-Ω) in series with the output, as shown in Figure 30.
This resistor significantly reduces the overshoot and ringing associated with large capacitive loads. A possible
problem with this technique is that a voltage divider is created with the added series resistor and any resistor
connected in parallel with the capacitive load. The voltage divider introduces a gain error at the output that
reduces the output swing. However, the error contributed by the voltage divider may be insignificant. For
example, with a load resistance of RL = 10 kΩ and RS = 20 Ω, the gain error is approximately 0.2%. When RL
decreases to 600 Ω (which the OPAx322-Q1 is able to drive), the error increases to 7.5%.

8.3.8 Overload Recovery Time
Overload recovery time is the time required for the output of the amplifier to come out of saturation and recover
to the linear region. Overload recovery is particularly important in applications where small signals must be
amplified in the presence of large transients. Figure 31 and Figure 32 show the positive and negative overload
recovery times of the OPAx322-Q1, respectively. In both cases, the time elapsed before the OPAx322-Q1 comes
out of saturation is less than 100 ns. The symmetry between the positive and negative recovery times allows
excellent signal rectification without distortion of the output signal.

9 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.
9.1 Application Information
The OPAx322-Q1 family offers outstanding DC and AC performance. These devices operate up to a 5.5-V power
supply and offer ultra-low input bias current and 20-MHz bandwidth. These features make the OPAx322-Q1
family a robust operational amplifier for both battery-powered and industrial applications.
9.1.1 Active Filter
The OPAx322-Q1 is well-suited for active filter applications that require a wide bandwidth, fast slew rate, lownoise, single-supply operational amplifier. Figure 33 shows a 500-kHz, second-order, low-pass filter using the
multiple-feedback (MFB) topology. The components are selected to provide a maximally flat Butterworth
response. Beyond the cutoff frequency, roll-off is –40 dB/dec. The Butterworth response is ideal for applications
that require predictable gain characteristics, such as the anti-aliasing filter used in front of an ADC.
One point to observe when considering the MFB filter is that the output is inverted relative to the input. If this
inversion is not required (or not desired) a noninverting output can be achieved through one of these options:
1. Adding an inverting amplifier
2. Adding an additional second-order MFB stage

10 Power Supply Recommendations
The OPAx322-Q1 family is specified for operation from 1.8 V to 5.5 V (±0.9 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 Typical Characteristics.
CAUTION
Supply voltages larger than 6 V can permanently damage the device; see the Absolute
Maximum Ratings.
Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or highimpedance power supplies. For more detailed information on bypass capacitor placement, see Layout.

11 Layout
11.1 Layout Guidelines
The OPAx322-Q1 is a wideband amplifier. To realize the full operational performance of the device, follow good
high-frequency printed-circuit board (PCB) layout practices. The bypass capacitors must be connected between
each supply pin and ground as close as possible to the device. The bypass capacitor traces must be designed
for minimum inductance.
