LM7332 Dual Rail-to-Rail Input/Output 30V, Wide Voltage Range, High Output Operational Amplifier General Description Features The LM7332 is a dual rail-to-rail input and output amplifier with a wide operating temperature range (−40°C to +125°C) which meets the needs of automotive, industrial and power supply applications. The LM7332 has the output current of 100 mA which is higher than that of most monolithic op amps. Circuit designs with high output current requirements often need to use discrete transistors because many op amps have low current output. The LM7332 has enough current output to drive many loads directly, saving the cost and space of the discrete transistors. The exceptionally wide operating supply voltage range of 2.5V to 32V alleviates any concerns over functionality under extreme conditions and offers flexibility of use in a multitude of applications. Most of this device's parameters are insensitive to power supply variations; this design enhancement is another step in simplifying usage. Greater than rail-to-rail input common mode voltage range allows operation in many applications, including high side and low side sensing, without exceeding the input range. The LM7332 can drive unlimited capacitive loads without oscillations. The LM7332 is offered in the 8-pin MSOP and SOIC packages.

RRIO with 100 mA Output Current The LM7332 takes advantages of National Semiconductor’s VIP3 process which enables high current driving from the rails. Rail-to-rail output swing provides the maximum possible output dynamic range. The LM7332 eliminates the need to use extra transistors when driving large capacitive loads, therefore reducing the application cost and space. -40°C to 125°C Operating Temperature Range The LM7332 has an operating temperature ranging from -40° C to 125°C, which is Automotive Grade 1, and also meets most industrial requirements. SOIC and MSOP Packages The LM7332 are offered in both the standard SOIC package and the space saving MSOP package. Please refer to the Physical Dimensions on page 17 for details. OUTPUT VOLTAGE SWING CLOSE TO V− The LM7332’s output stage design allows voltage swings to within millivolts of either supply rail for maximum flexibility and improved useful range. Because of this design architecture, with output approaching either supply rail, the output transistor Collector-Base junction reverse bias will decrease. With output less than a Vbe from either rail, the corresponding output transistor operates near saturation. In this mode of operation, the transistor will exhibit higher junction capacitance and lower ft which will reduce phase margin. With the Noise Gain (NG = 1 + RF/RG, RF and RG are external gain setting resistors) of 2 or higher, there is sufficient phase margin that this reduction in phase margin is of no consequence. However, with lower Noise Gain (<2) and with less than 150 mV to the supply rail, if the output loading is light, the phase margin reduction could result in unwanted oscillations. In the case of the LM7332, due to inherent architectural specifics, the oscillation occurs only with respect to the output transistor at V− when output swings to within 150 mV of V−. However, if this output transistor's collector current is larger than its idle value of a few microamps, the phase margin loss becomes insignificant. In this case, 300 μA is the required output transistor's collector current to remedy this situation. Therefore, when all the aforementioned critical conditions are present at the same time (NG < 2, VOUT < 150 mV from supply rails, & output load is light) it is possible to ensure stability by adding a load resistor to the output to provide the output transistor the necessary minimum collector current (300 μA). For 12V (or ±6V) operation, for example, add a 39 kΩ resistor from the output to V+ to cause 300 µA output sinking current and ensure stability. This is equivalent to about 15% increase in total quiescent power dissipation. 20187579 FIGURE 1. Settling Time and Slew Rate vs. Capacitive Load ESTIMATING THE OUTPUT VOLTAGE SWING It is important to keep in mind that the steady state output current will be less than the current available when there is an input overdrive present. For steady state conditions, Figure 2 and Figure 3 plots can be used to predict the output swing. These plots also show several load lines corresponding to loads tied between the output and ground. In each case, the intersection of the device plot at the appropriate temperature with the load line would be the typical output swing possible for that load. For example, a 600Ω load can accommodate an output swing to within 100 mV of V− and to 250 mV of V+ (VS = ±5V) corresponding to a typical 9.65 VPP unclipped swing. 15 www.national.com LM7332 DRIVING CAPACITIVE LOADS The LM7332 is specifically designed to drive unlimited capacitive loads without oscillations. In addition, the output current handling capability of the device allows for good slewing characteristics even with large capacitive loads as shown in Figure 1. The combination of these features is ideal for applications such as TFT flat panel buffers, A/D converter input amplifiers and power transistor driver. However, as in most op amps, addition of a series isolation resistor between the op amp and the capacitive load improves the settling and overshoot performance. Output current drive is an important parameter when driving capacitive loads. This parameter will determine how fast the output voltage can change. Referring to Figure 1, two distinct regions can be identified. Below about 10,000 pF, the output Slew Rate is solely determined by the op amp’s compensation capacitor value and available current into that capacitor. Beyond 10 nF, the Slew Rate is determined by the op amp’s available output current. An estimate of positive and negative slew rates for loads larger than 100 nF can be made by dividing the short circuit current value by the capacitor. Application Information LM7332 offset, or the output AC average current is non-zero, or if the op amp operates in a single supply application where the output is maintained somewhere in the range of linear operation. Therefore: PTOTAL = PQ + PDC + PAC PQ = IS · VS Op Amp Quiescent Power Dissipation DC Load Power PDC = IO · (Vr - Vo) PAC = See Table 1 below AC Load Power where: IS: Supply Current VS: Total Supply Voltage (V+ − V−) VO: Average Output Voltage Vr: V+ for sourcing and V− for sinking current Table 1 below shows the maximum AC component of the load power dissipated by the op amp for standard Sinusoidal, Triangular, and Square Waveforms: 20187590 FIGURE 2. Steady State Output Sourcing Characteristics with Load Lines TABLE 1. Normalized AC Power Dissipated in the Output Stage for Standard Waveforms PAC (W.Ω/V2) Sinusoidal Triangular Square 50.7 x 10−3 46.9 x 10−3 62.5 x 10−3 The table entries are normalized to VS2/RL. To figure out the AC load current component of power dissipation, simply multiply the table entry corresponding to the output waveform by the factor VS2/RL. For example, with ±12V supplies, a 600Ω load, and triangular waveform power dissipation in the output stage is calculated as: PAC = (46.9 x 10−3) · [242/600] = 45.0 mW The maximum power dissipation allowed at a certain temperature is a function of maximum die junction temperature (TJ (MAX)) allowed, ambient temperature TA, and package thermal resistance from junction to ambient, θJA. 20187591 FIGURE 3. Steady State Output Sinking Characteristics with Load Lines OUTPUT SHORT CIRCUIT CURRENT AND DISSIPATION ISSUES The LM7332 output stage is designed for maximum output current capability. Even though momentary output shorts to ground and either supply can be tolerated at all operating voltages, longer lasting short conditions can cause the junction temperature to rise beyond the absolute maximum rating of the device, especially at higher supply voltage conditions. Below supply voltage of 6V, the output short circuit condition can be tolerated indefinitely. With the op amp tied to a load, the device power dissipation consists of the quiescent power due to the supply current flow into the device, in addition to power dissipation due to the load current. The load portion of the power itself could include an average value (due to a DC load current) and an AC component. DC load current would flow if there is an output voltage www.national.com For the LM7332, the maximum junction temperature allowed is 150°C at which no power dissipation is allowed. The power capability at 25°C is given by the following calculations: For MSOP package: For SOIC package: 16 For MSOP package: APPLICATION HINTS ON SUPPLY DECOUPLING The use of supply decoupling is mandatory in most applications. As with most relatively high speed/high output current op amps, best results are achieved when each supply line is decoupled with two capacitors; a small value ceramic capacitor (∼0.01 µF) placed very close to the supply lead in addition to a large value Tantalum or Aluminum capacitor (> 4.7 µF). The large capacitor can be shared by more than one device if necessary. The small ceramic capacitor maintains low supply impedance at high frequencies while the large capacitor will act as the charge “bucket” for fast load current spikes at the op amp output. The combination of these capacitors will provide supply decoupling and will help keep the op amp oscillation free under any load. For SOIC package: Figure 4 shows the power capability vs. temperature for MSOP and SOIC packages. The area under the maximum thermal capability line is the operating area for the device. When the device works in the operating area where PTOTAL is less than PD(MAX), the device junction temperature will remain below 150°C. If the intersection of ambient temperature and package power is above the maximum thermal capability line, the junction temperature will exceed 150°C and this should be strictly prohibited. SIMILAR HIGH CURRENT OUTPUT DEVICES The LM6172 has a higher GBW of 100 MHz and over 80 mA of current output. There is also a single version, the LM6171. The LM7372 has 120 MHz of GBW and 150 mA of current output. The LM7372 is available in a small pin LLP package, an 8-pin PSOP, and 16-pin SOIC packages with higher power dissipation. The LME49600 buffer has 250 mA of current out and a 110 MHz bandwidth. The LME49600 is available in a TO-263 package for higher power dissipation.
