A complementary input stage—an N-channel input differential pair in parallel with a P-channel differential pair—achieves this extension. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.2 V to 100 mV above the positive supply, while the P-channel pair is on for inputs from 100 mV below the negative supply to approximately (V+) – 1.2 V. A small transition region exists, typically (V+) – 1.5 V to (V+) – 0.9 V, in which both pairs are on. This 600-mV transition region can vary ±500 mV with process variation. Thus, the transition region (both input stages on) can range from (V+) – 2 V to (V+) – 1.5 V on the low end, up to (V+) – 0.9 V to (V+) – 0.4 V on the high end. A double-folded cascode adds the signal from the two input pairs and presents a differential signal to the class AB output stage. 7.3.3 Rail-to-Rail Output The device uses a class-AB output stage with common-source transistors to achieve rail-to-rail output. For highimpedance loads (> 200 Ω), the output voltage swing is typically 100 mV from the supply rails. With 10-Ω loads, one can achieve a useful output swing while maintaining high open-loop gain. See Figure 20, Output Voltage Swing vs Output Current. 7.3.4 Output Drive The OPAx354-Q1 output stage can supply a continuous output current of ±100 mA and still provide approximately 2.7-V output swing on a 5-V supply, as shown in Figure 30.

Parallel Operation The OPAx354-Q1 family of devices provides peak currents up to 200 mA, which corresponds to the typical shortcircuit current. Therefore, an on-chip thermal shutdown circuit protects the OPAx354-Q1 family of devices from dangerously high junction temperatures. At 160°C, the protection circuit shuts down the amplifier. Normal operation resumes when the junction temperature cools below 140°C. 7.3.5 Video The OPAx354-Q1 output stage is capable of driving standard back-terminated 75-Ω video cables (see Figure 32). A back-terminated transmission line does not exhibit a capacitive load to its driver.

RGB Cable Driver 7.3.6 Driving Analog-to-Digital Converters The OPAx354-Q1 family of op-amps offers a 60-ns settling time to 0.01%, making the devices a good choice for driving high- and medium-speed sampling ADCs and reference circuits. The OPAx354-Q1 family of devices provides an effective means of buffering the input capacitance and resulting charge injection of the ADC while providing signal gain. The OPAx354-Q1 family of devices is ideal for applications requiring high DC accuracy. Figure 34 shows the OPAx354-Q1 family of devices driving an ADC.

OPA354-Q1 Inverting Configuration Driving the ADS7816 7.3.7 Capacitive Load and Stability The OPAx354-Q1 family op-amps can drive a wide range of capacitive loads. However, all op-amps under certain conditions can 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 most susceptible to the effects of capacitive loading. The capacitive load reacts with the output resistance of the op-amp, along with any additional load resistance, to create a pole in the small-signal response that degrades the phase margin. For details see Figure 15, Frequency Response vs Capacitive Load. The OPAx354-Q1 topology enhances the ability of the device to drive capacitive loads. In unity gain, these opamps perform well with large capacitive loads. For details see Figure 14, Recommended RS vs Capacitive Load, and Figure 15, Frequency Response vs Capacitive Load. One method of improving capacitive load drive in the unity-gain configuration is to insert a 10-Ω to 20-Ω resistor in series with the output, as shown in Figure 35. This configuration significantly reduces ringing with large capacitive loads—see Figure 15, Frequency Response vs Capacitive Load. However, if a resistive load is in parallel with the capacitive load, RS creates a voltage divider. This configuration introduces a DC error at the output and slightly reduces output swing. This error may be insignificant. For instance, with RL = 10 kΩ and RS = 20 Ω, the error at the output is only about a 0.2%. V+ RS VOUT OPA354-Q1 VIN RL CL Figure 35. Series Resistor in Unity-Gain Configuration Improves Capacitive Load Drive 7.3.8 Wideband Transimpedance Amplifier Wide bandwidth, low-input bias current, and low input voltage and current noise make the OPAx354-Q1 family of devices an ideal wideband photodiode transimpedance amplifier for low-voltage single-supply applications. Lowvoltage noise is important because photodiode capacitance causes the effective noise gain of the circuit to increase at high frequency. 16 Submit Documentation Feedback Copyright © 2009–2014, Texas Instruments Incorporated Product Folder Links: OPA354-Q1 OPA2354-Q1 OPA4354-Q1 OPA354-Q1, OPA2354-Q1, OPA4354-Q1 www.ti.com SBOS492B – JUNE 2009 – REVISED DECEMBER 2014 Feature Description (continued) The key elements to a transimpedance design, as shown in Figure 36, are the expected diode capacitance (including the parasitic input common-mode and differential-mode input capacitance (2 + 2) pF for the OPAx354Q1), the desired transimpedance gain (RF), and the gain-bandwidth product (GBW) for the OPAx354-Q1 family of devices (100 MHz).

The devices can be operated as single supply operational amplifiers or dual supply amplifiers depending on the application. The devices can also be used with asymmetrical supplies as long as the differential voltage (V– to V+) is at least 1.8 V and no greater than 5.5 V (example: V– set to –3.5 V and V+ set to 1.5 V).

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 OPAx354-Q1 family of devices is a CMOS, rail-to-rail I/O, high-speed, voltage-feedback operational amplifier designed for video, high-speed, and other applications. The OPAx354-Q1 family of devices is available as a single, dual, or quad op-amp. The amplifier features a 100-MHz gain bandwidth, and 150 V/μs slew rate, but it is unity-gain stable and can be operated as a 1-V/V voltage follower. 8.2 Typical Applications 8.2.1 Transimpedance Amplifier Wide gain bandwidth, low input bias current, low input voltage, and current noise make the OPAx354-Q1 family of devices an ideal wideband photodiode transimpedance amplifier. Low-voltage noise is important because photodiode capacitance causes the effective noise gain of the circuit to increase at high frequency. The key elements to a transimpedance design, as shown in Figure 37, are the expected diode capacitance (C(D)), which should include the parasitic input common-mode and differential-mode input capacitance (4 pF + 5 pF); the desired transimpedance gain (R(FB)); and the gain-bandwidth (GBW) for the OPAx354-Q1 family of devices (20 MHz). With these three variables set, the feedback capacitor value (C(FB)) can be set to control the frequency response.

For single-supply applications, the +INx input can be biased with a positive DC voltage to allow the output to reach true zero when the photodiode is not exposed to any light, and respond without the added delay that results from coming out of the negative rail; this configuration is shown in Figure 38. This bias voltage also appears across the photodiode, providing a reverse bias for faster operation. 0.5 pF 100 k ± OPAx354-Q1 VOUT + 13.7 k SFH213 1 F 280 5V Figure 38. Single-Supply Transimpedance Amplifier For additional information, refer to the application bulletin from TI, Compensate Transimpedance Amplifiers Intuitively (SBOA055). 8.2.1.2.1 Optimizing The Transimpedance Circuit To achieve the best performance, components should be selected according to the following guidelines: 1. For lowest noise, select R(FB) to create the total required gain. Using a lower value for R(FB) and adding gain after the transimpedance amplifier generally produces poorer noise performance. The noise produced by R(FB) increases with the square-root of R(FB), whereas the signal increases linearly. Therefore, signal-to-noise ratio improves when all the required gain is placed in the transimpedance stage. 2. Minimize photodiode capacitance and stray capacitance at the summing junction (inverting input). This capacitance causes the voltage noise of the op amp to be amplified (increasing amplification at high frequency). Using a low-noise voltage source to reverse-bias a photodiode can significantly reduce the capacitance. Smaller photodiodes have lower capacitance. Use optics to concentrate light on a small photodiode. 3. Noise increases with increased bandwidth. Limit the circuit bandwidth to only that required.

Circuit board leakage can degrade the performance of an otherwise well-designed amplifier. Clean the circuit board carefully. A circuit board guard trace that encircles the summing junction and is driven at the same voltage can help control leakage. For additional information, refer to the following application bulletins from TI: Noise Analysis of FET Transimpedance Amplifiers (SBOA060), and Noise Analysis for High-Speed Op Amps (SBOA066). 8.2.1.3 Application Curve 105 100 Gain (dB, V/A) 95 90 85 80 75 70 65 60 1000 10000 100000 1000000 Frequency (Hz) 1E+7 5E+7 D001 –3 dB bandwidth is 4.56 MHz Figure 39. AC Transfer Function 8.2.2 High-Impedance Sensor Interface Many sensors have high source impedances that may range up to 10 MΩ, or even higher. The output signal of sensors often must be amplified or otherwise conditioned by means of an amplifier. The input bias current of this amplifier can load the sensor output and cause a voltage drop across the source resistance, as shown in Figure 40, where (V(+INx) = VS – I(BIAS) × R(S)). The last term, I(BIAS) × R(S), shows the voltage drop across R(S). To prevent errors introduced to the system as a result of this voltage, an op amp with very low input bias current must be used with high impedance sensors. This low current keeps the error contribution by I(BIAS) × R(S) less than the input voltage noise of the amplifier, so that it does not become the dominant noise factor. The OPAx354-Q1 family of devices series of op amps feature very low input bias current (typically 200 fA), and are therefore ideal choices for such applications.

The zero-crossover distortion input stage topology allows the OPAx354-Q1 family of devices to drive ADCs without degradation of differential linearity and THD. The OPAx354-Q1 family of devices can be used to buffer the ADC switched input capacitance and resulting charge injection while providing signal gain.

Driving the ADS8326 8.2.4 Active Filter The OPAx354-Q1 family of devices is well-suited for active filter applications that require a wide bandwidth, fast slew rate, low-noise, single-supply operational amplifier. Figure 42 shows a 500 kHz, second-order, low-pass filter using the multiple-feedback (MFB) topology. The components have been selected to provide a maximallyflat Butterworth response. Beyond the cutoff frequency, roll-off is –40 dB/dec. The Butterworth response is ideal for applications requiring 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 the following 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 (see Figure 43). MFB and 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.

Parameters that can exhibit significant variance with regard to operating voltage or temperature are shown in the Typical Characteristics section. CAUTION Supply voltages larger than 7.5 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 highimpedance power supplies. For more detailed information on bypass capacitor placement, refer to the Layout Guidelines section. 22 Submit Documentation Feedback Copyright © 2009–2014, Texas Instruments Incorporated Product Folder Links: OPA354-Q1 OPA2354-Q1 OPA4354-Q1 OPA354-Q1, OPA2354-Q1, OPA4354-Q1 www.ti.com SBOS492B – JUNE 2009 – REVISED DECEMBER 2014 9.1 Power Dissipation Power dissipation depends on power-supply voltage, signal and load conditions. With dc signals, power dissipation is equal to the product of output current times the voltage across the conducting output transistor, VS – VO. Minimize power dissipation by using the lowest possible power-supply voltage necessary to assure the required output voltage swing. For resistive loads, the maximum power dissipation occurs at a dc output voltage of one-half the power-supply voltage. Dissipation with ac signals is lower. Application bulletin AB-039 (SBOA022), Power Amplifier Stress and Power Handling Limitations, explains how to calculate or measure power dissipation with unusual signals and loads, and can be found at www.ti.com. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heatsink. For reliable operation, limit junction temperature to 150°C, maximum. To estimate the margin of safety in a complete design, increase the ambient temperature to trigger the thermal protection at 160°C. The thermal protection should trigger more than 35°C above the maximum expected ambient condition of the application. 10 Layout 10.1 Layout Guidelines Use good high-frequency printed circuit board (PCB) layout techniques for the OPAx354-Q1 family of devices. Generous use of ground planes, short and direct signal traces, and a suitable bypass capacitor located at the V+ pin assure clean stable operation. Large areas of copper also provides a means of dissipating heat that is generated in normal operation. Sockets are not recommended for use with any high-speed amplifier. A 10-nF ceramic bypass capacitor is the minimum recommended value; adding a 1-μF or larger tantalum capacitor in parallel can be beneficial when driving a low-resistance load. Providing adequate bypass capacitance is essential to achieving very low harmonic and intermodulation distortion. For best operational performance of the device, use good PCB layout practices, including: • Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the operational amplifier. Bypass capacitors are used to reduce the coupled noise by providing lowimpedance power sources local to the analog circuitry. – Connect low-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 singlesupply applications. • Separate grounding for analog and digital portions of the circuitry is one of the simplest and most effective 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. Make sure to physically separate digital and analog grounds, paying attention to the flow of the ground current. For more detailed information, refer to Circuit Board Layout Techniques, SLOA089. • 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 perpendicularly is much better than crossing in parallel with the noisy trace. • Place the external components as close to the device as possible. Keeping RF and RG close to the inverting input minimizes parasitic capacitance, as shown in Figure 44. • 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.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
