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/µs 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.

Detailed Description Choosing Resistor Values The MAX4380–MAX4384 are single-supply, rail-to-rail, voltage-feedback amplifiers that employ current-feedback techniques to achieve 485V/µs 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. Unity-Gain Configuration The MAX4380–MAX4384 are internally compensated for unity gain. When configured for unity gain, a 24Ω 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. 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. 10 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.

Noninverting Gain Configuration RG RF IN VOUT MAX438 _ VOUT = -(RF / RG) VIN • 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. Rail-to-Rail Outputs, Ground-Sensing Inputs Figure 1b. Inverting Gain Configuration have a 16ns settling time to 0.1%, 485V/µs 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 1kΩ 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 1kΩ 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 These amplifiers operate from a single +4.5V to +11V power supply or from dual ±2.25V to ±5.5V supplies. For 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 2kΩ 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 35kΩ. 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. ______________________________________________________________________________________ 11 MAX4380–MAX4384 RG single-supply operation, bypass VCC to ground with a 0.1µF capacitor as close to the pin as possible. If operating with dual supplies, bypass each supply with a 0.1µF 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. RF RG 6 5 RISO CL = 15pF 4 VOUT VIN CL Figure 2.

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. 12 -5 -6 -7 100k 1M 10M 100M 1G FREQUENCY (Hz) Figure 5.
