General Description
The MAX4389/MAX4390/MAX4392–MAX4396 family of op amps are unity-gain stable devices that combine high-speed performance, rail-to-rail outputs, and dis­able mode. These devices are targeted for applications where an input or an output is exposed to the outside world, such as video and communications.
-3dB bandwidth, 27MHz 0.1dB gain flatness, and a 500V/µs slew rate. Disable mode sets the outputs to high impedance while consuming only 450µA of current.
The MAX4389 single, MAX4393 dual, MAX4394 triple, and MAX4396 quad include disable capabilities. The MAX4389 and MAX4390 are available in ultra-small, 6-pin SC70 packages.

ABSOLUTE MAXIMUM RATINGS
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 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 MAX4389/MAX4390/MAX4392–MAX4396 are dual­supply, rail-to-rail, voltage-feedback amplifiers that employ current-feedback techniques to achieve 500V/µs slew rates and 85MHz 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.
Applications Information
The output voltage swings to within 200mV 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 to the negative supply and to within 2.25V of the positive supply rail.
Choosing Resistor Values
Unity-Gain Configuration
The MAX4389/MAX4390/MAX4392–MAX4396 are inter­nally compensated for unity gain. When configured for unity gain, a 24Ω resistor (R
F
) 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 MAX4389/MAX4390/MAX4392–MAX4396 are low­power, voltage-feedback amplifiers featuring large-sig­nal (2V
P-P
) bandwidths of 90MHz and 0.1dB large­signal gain flatness of 24MHz. They are designed to minimize differential-gain error and differential-phase error to 0.015% and 0.015°, respectively. They have a 21ns settling time to 0.1%, 500V/µs slew rates, and out­put-current-drive capability of up to 50mA 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 (R
F
= RG) using 2kΩ resistors, combined with 1pF of amplifier input capaci­tance and 1pF of PC board capacitance, causes a pole at 79.6MHz. Since this pole is within the amplifier band­width, it jeopardizes stability. Reducing the 2kΩ resis­tors to 100Ω extends the pole frequency to 1.59GHz, but could limit output swing by adding 200Ω in parallel with the amplifier’s load resistor (Figures 1a and 1b).
Layout and Power-Supply Bypassing
The MAX4389/MAX4390/MAX4392–MAX4396 operate from single 4.5V to 11V or from dual ±2.25V to ±5.5V supplies. Bypass each supply with a 0.1µF capacitor as close to the pin as possible.
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:
• Do not use wire-wrap boards; they are too inductive.
• Do not 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.
Low-Power Disable Mode
The MAX4389/MAX4393/MAX4394/MAX4396 feature a disable function that allows the amplifiers to be placed in a low-power, high-output-impedance state. When the disable pin (DISABLE) is active, the amplifier’s output impedance is 95kΩ. This high resistance and the low 2pF output capacitance make the MAX4389/ MAX4390/MAX4392–MAX4396 in RF/video multiplexer or switch applications. For larger arrays, pay careful attention to capacitive loading (see the
Output
Capacitive Loading and Stability
section).
Output Capacitive Loading and Stability
The MAX4389/MAX4390/MAX4392–MAX4396 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 10Ω to 15Ω) 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 15Ω isolation resistor on closed-loop response.
