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. 8.2 Functional Block Diagram V+ Low Noise Charge Pump Bias Circuitry +IN -IN OUT Input Stage Load Bias Circuitry VCopyright © 2016, Texas Instruments Incorporated 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. 16 Submit Documentation Feedback Copyright © 2013–2017, Texas Instruments Incorporated Product Folder Links: OPA322-Q1 OPA2322-Q1 OPA4322-Q1 OPA322-Q1 OPA2322-Q1 OPA4322-Q1 www.ti.com SLOS856B – JUNE 2013 – REVISED MAY 2017 Feature Description (continued) V+ IOVERLOAD 10 mA, maximum VOUT OPA322-Q1 VIN RS Copyright © 2016, Texas Instruments Incorporated Figure 26. Input Current Protection 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. 4 VIN VS = ±2.5 V 3 Voltage (V) 2 VOUT 1 0 -1 -2 -3 -4 -500 -250 0 250 500 750 1000 Time (ms) Figure 27. No 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.

RIN × CIN = RF × CF where • CIN is equal to the OPAx322-Q1 input capacitance (sum of differential and common-mode) plus the layout capacitance (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%. 18 Submit Documentation Feedback Copyright © 2013–2017, Texas Instruments Incorporated Product Folder Links: OPA322-Q1 OPA2322-Q1 OPA4322-Q1 OPA322-Q1 OPA2322-Q1 OPA4322-Q1 www.ti.com SLOS856B – JUNE 2013 – REVISED MAY 2017 Feature Description (continued) 70 G = 1, VS = 1.8 V 60 G = 1, VS = 5.5 V G = 10, VS = 1.8 V Overshoot (%) 50 G = 10, VS = 5.5 V 40 30 20 10 0 0 500 1000 1500 2000 3000 2500 Capacitive Load (pF) Figure 29.

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. spacer 3 2.5 Output 0.5 Input 2 0 1.5 -0.5 Voltage (V) Voltage (V) 1 VS = ±2.75 V G = -10 1 0.5 0 -1 -1.5 -2 Input Output -0.5 VS = ±2.75 V G = -10 -2.5 -1 9.75 10 10.25 10.5 10.75 11 -3 9.75 10 10.25 Time (250 ns/div) Figure 31.

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 3. Using a noninverting filter topology, such as the Sallen-Key (shown in Figure 34). MFB, Sallen-Key, low-pass, and high-pass filter synthesis is quickly accomplished using TI’s FilterPro™ program. This software is available as a free download at www.ti.com.

Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will thoroughly test such applications and the functionality of such TI products as used in such applications. TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource solely for this purpose and subject to the terms of this Notice. TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically described in the published documentation for a particular TI Resource. Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI products or services are used.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection.
