1 9-7; Rev ; / EVALUATION KIT MANUAL AVAILABLE Miniature, MHz, Single-Supply, General Description The MAX/MAX single, MAX dual, MAX triple, and MAX quad op amps are unity-gain-stable devices that combine high-speed performance with Rail-to-Rail outputs. The MAX/ MAX have a disable feature that reduces powersupply current to µa and places the outputs into a high-impedance state. These devices operate from a.v to V single supply or from ±.V to ±V dual supplies. The common-mode input voltage range extends beyond the negative power-supply rail (ground in single-supply applications). These devices require only.ma of quiescent supply current while achieving a MHz -db bandwidth and a V/µs slew rate. Input-voltage noise is only nv/ Hz and input-current noise is only.pa/ Hz for either the inverting or noninverting input. These parts are an excellent solution in low-power/low-voltage systems that require wide bandwidth, such as video, communications, and instrumentation. In addition, when disabled, their high-output impedance makes them ideal for multiplexing applications. The MAX comes in a miniature -pin SOT package, while the MAX/MAX come in -pin µmax and SO packages. The MAX/MAX are available in space-saving -pin QSOP and -pin SO packages.

10 Miniature, MHz, Single-Supply, MAX/MAX/MAX/MAX/MAX Detailed Description The MAX/MAX/MAX/MAX/MAX are single-supply, rail-to-rail, voltage-feedback amplifiers that employ current-feedback techniques to achieve V/µs slew rates and MHz bandwidths. Excellent harmonic distortion and differential gain/ phase performance make these amplifiers an ideal choice for a wide variety of video and RF signalprocessing applications. The output voltage swing comes to within mv of each supply rail. Local feedback around the output stage assures low open-loop output impedance to reduce gain sensitivity to load variations. This feedback also produces demand-driven current bias to the output transistors for ±ma drive capability, while constraining total supply current to less than 7mA. The input stage permits common-mode voltages beyond the negative supply and to within.v of the positive supply rail. Applications Information Choosing Resistor Values Unity-Gain Configuration The MAX/MAX/MAX/MAX/MAX are internally compensated for unity gain. When configured for unity gain, the devices require a Ω resistor (RF) in series with the feedback path. This resistor R G R T R F R TO V = [+ (R F / R G )] V V R O improves AC response by reducing the Q of the parallel LC circuit formed by the parasitic feedback capacitance and inductance. Inverting and Noninverting Configurations Select the gain-setting feedback (R F ) and input (R G ) resistor values to fit your application. Large resistor values increase voltage noise and interact with the amplifier s input and PC board capacitance. This can generate undesirable poles and zeros and decrease bandwidth or cause oscillations. For example, a noninverting gain-of-two configuration (R F = R G ) using kω resistors, combined with pf of amplifier input capacitance and pf of PC board capacitance, causes a pole at 9MHz. Since this pole is within the amplifier bandwidth, it jeopardizes stability. Reducing the kω resistors to Ω extends the pole frequency to.9ghz, but could limit output swing by adding Ω in parallel with the amplifier s load resistor. Table shows suggested feedback, gain resistors, and bandwidth for several gain values in the configurations shown in Figures a and b. Layout and Power-Supply Bypassing These amplifiers operate from a single.v to V power supply or from dual supplies to ±.V. For single-supply operation, bypass VCC to ground with a.µf capacitor as close to the pin as possible. If operating with dual supplies, bypass each supply with a.µf capacitor.

11 Miniature, MHz, Single-Supply, Maxim recommends using microstrip and stripline techniques to obtain full bandwidth. To ensure that the PC board does not degrade the amplifier s performance, design it for a frequency greater than GHz. Pay careful attention to inputs and outputs to avoid large parasitic capacitance. Whether or not you use a constantimpedance board, observe the following guidelines when designing the board: Don t use wire-wrap boards because they are too inductive. Don t use IC sockets because they increase parasitic capacitance and inductance. Use surface-mount instead of through-hole components for better high-frequency performance. Use a PC board with at least two layers; it should be as free from voids as possible. Keep signal lines as short and as straight as possible. Do not make 9 turns; round all corners. Rail-to-Rail Outputs, Ground-Sensing Input The input common-mode range extends from (VEE - mv) to (V CC -.V) with excellent commonmode rejection. Beyond this range, the amplifier output is a nonlinear function of the input, but does not undergo phase reversal or latchup. Table. Recommended Component Values R F (Ω) R G (Ω) R S (Ω) R T (Ω) R TO (Ω) Note: COMPONENT Small-Signal -db Bandwidth (MHz) The output swings to within mv of either powersupply rail with a kω load. The input ground-sensing and the rail-to-rail output substantially increase the dynamic range. With a symmetric input in a single V application, the input can swing.9v P-P, and the output can swing.9v P-P with minimal distortion. Enable Input and Disabled Output The enable feature (EN_) allows the amplifier to be placed in a low-power, high-output-impedance state. Typically, the EN_ logic low input current (I IL ) is small. However, as the EN voltage (V IL ) approaches the negative supply rail, I IL increases (Figure ). A single resistor connected as shown in Figure prevents the rise in the logic-low input current. This resistor provides a feedback mechanism that increases V IL as the logic input is brought to V EE. Figure shows the resulting input current (I IL ). When the MAX/MAX are disabled, the amplifier s output impedance is kω. This high resistance and the low pf output capacitance make these parts ideal in RF/video multiplexer or switch applications. For larger arrays, pay careful attention to capacitive loading. See the Output Capacitive Loading and Stability section for more information. R L = R O + R TO ; R T and R TO are calculated for Ω applications. For 7Ω systems, R TO = 7Ω; calculate R T from the following equation: 7 R T = - 7 Ω RG - GA (V/V) MAX/MAX/MAX/MAX/MAX

Enable Logic-Low Input Current vs. V IL with kω Series Resistor - + ENABLE MAX kω EN_ Figure. Circuit to Reduce Enable Logic-Low Input Current Output Capacitive Loading and Stability The MAX/MAX/MAX/MAX/MAX are optimized for AC performance. They are not designed to drive highly reactive loads, which decreases phase margin and may produce excessive ringing and oscillation. Figure shows a circuit that eliminates this problem. Figure is a graph of the optimal isolation resistor (RS) vs. capacitive load. Figure 7 shows how a capacitive load causes excessive peaking of the amplifier s frequency response if the capacitor is not isolated from the amplifier by a resistor. A small isolation resistor (usually Ω to Ω) placed before the reactive load prevents ringing and oscillation. At higher capacitive loads, AC performance is controlled by the interaction of the load capacitance and the isolation resistor. Figure shows the effect of a 7Ω isolation resistor on closed-loop response. Coaxial cable and other transmission lines are easily driven when properly terminated at both ends with their characteristic impedance. Driving back-terminated transmission lines essentially eliminates the line s capacitance.
