Ultra-Small, Low-Cost, 210MHz, Single-Supply Op Amps with Rail-to-Rail Outputs and Disable MAX4380-MAX4384
General Description
The MAX4380-MAX4384 family of op amps are unitygain-stable devices that combine high-speed performance, Rail-to-Rail (R) outputs, and high-impedance disable mode. These devices operate from a +4.5V to +11V single supply or from 2.25V to 5.5V dual supplies. The common-mode input voltage range extends beyond the negative power-supply rail (ground in single-supply applications). The MAX4380-MAX4384 require only 5.5mA of quiescent supply current per op amp while achieving a 210MHz -3dB bandwidth, 55MHz 0.1dB gain flatness and a 485V/s slew rate. These devices are an excellent solution in low-power/low-voltage systems that require wide bandwidth, such as video, communications, and instrumentation. The MAX4380 single with disable is available in an ultrasmall 6-pin SC70 package. o Low Cost and High Speed: 210MHz -3dB Bandwidth 55MHz 0.1dB Gain Flatness 485V/s Slew Rate o Disable Mode Places Outputs in High-Impedance State o Single +4.5V to +11V Operation o Rail-to-Rail Outputs o Input Common-Mode Range Extends Beyond VEE o Low Differential Gain/Phase: 0.02%/0.08 o Low Distortion at 5MHz -65dBc SFDR -63dB Total Harmonic Distortion o Ultra-Small 6-Pin SC70, 6-Pin SOT23, 10-Pin MAX, 14-Pin TSSOP, and 20-Pin TSSOP Packages

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or at any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX4380-MAX4384 are single-supply, rail-to-rail, voltage-feedback amplifiers that employ current-feedback techniques to achieve 485V/s slew rates and 210MHz bandwidths. Excellent harmonic distortion and differential gain/phase performance make these amplifiers an ideal choice for a wide variety of video and RF signal-processing applications.
Choosing Resistor Values
Unity-Gain Configuration The MAX4380-MAX4384 are internally compensated for unity gain. When configured for unity gain, a 24 resistor (RF) in series with the feedback path optimizes AC performance. This resistor improves AC response by reducing the Q of the parallel LC circuit formed by the parasitic feedback capacitance and inductance. Video Line Driver The MAX4380-MAX4384 are low-power, voltage-feedback amplifiers featuring bandwidths up to 210MHz, 0.1dB gain flatness to 55MHz. They are designed to minimize differential-gain error and differential-phase error to 0.02% and 0.08 degrees respectively. They
Applications Information
The output voltage swings to within 50mV of each supply rail. Local feedback around the output stage ensures low open-loop output impedance to reduce gain sensitivity to load variations. The input stage permits common-mode voltages beyond the negative supply and to within 2.25V of the positive supply rail.

single-supply operation, bypass VCC to ground with a 0.1F capacitor as close to the pin as possible. If operating with dual supplies, bypass each supply with a 0.1F capacitor. 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 1GHz. Pay careful attention to inputs and outputs to avoid large parasitic capacitance. Whether or not you use a constant-impedance board, observe the following design guidelines: * Don't use wire-wrap boards; they are too inductive. * Don't use IC sockets; 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 90 turns; round all corners.

have a 16ns settling time to 0.1%, 485V/s slew rates, and output-current-drive capability of up to 75mA making them ideal for driving video loads. Inverting and Noninverting Configurations Select the gain-setting feedback (RF) and input (RG) 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 (RF = RG) using 1k resistors, combined with 1pF of amplifier input capacitance and 1pF of PC board capacitance, causes a pole at 159MHz. Since this pole is within the amplifier bandwidth, it jeopardizes stability. Reducing the 1k resistors to 100 extends the pole frequency to 1.59GHz, but could limit output swing by adding 200 in parallel with the amplifier's load resistor (Figures 1a and 1b).
For +5V single-supply operation, the input commonmode range extends from (V EE - 200mV) to (V CC - 2.25V) with excellent common-mode rejection. Beyond this range, the amplifier output is a nonlinear function of the input, but does not undergo phase reversal or latchup. For 5V dual-supply operation, the common-mode range is from VEE to (VCC - 2.25V) For +5V single-supply operation the output swings to within 50mV of either power-supply rail with a 2k load. The input ground sensing and the rail-to-rail output substantially increase the dynamic range. With a symmetric input in a single +5V application, the input can swing 2.95Vp-p and the output can swing 4.9Vp-p with minimal distortion.
Low-Power Disable Mode
The disable feature (DISABLE_) allows the amplifier to be placed in a low-power, high-output-impedance state. When the disable pin (DISABLE_) is active, the amplifier's output impedance is 35k. This high resistance and the low 2pF output capacitance make the MAX4380-MAX4382 and the MAX4384 ideal in RF/video multiplexer or switch applications. For larger arrays, pay careful attention to capacitive loading. Refer to the Output Capacitive Loading and Stability section.

Output Capacitive Loading and Stability
The MAX4380-MAX4384 are optimized for AC performance. They are not designed to drive highly reactive loads, which decrease phase margin and may produce excessive ringing and oscillation. Figure 2 shows a circuit that eliminates this problem. Figure 3 is a graph of the Optimal Isolation Resistor (RS) vs. Capacitive Load. Figure 4 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 10 to 15) 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 5 shows the effect of a 15 isolation resistor on closed-loop response.
