MAX4200-MAX4205 Ultra-High-Speed, Low-Noise, Low-Power, SOT23 Open-Loop Buffers General Description The MAX4200-MAX4205 are ultra-high-speed, openloop buffers featuring high slew rate, high output current, low noise, and excellent capacitive-load-driving capability. The MAX4200/MAX4201/MAX4202 are single buffers, while the MAX4203/MAX4204/MAX4205 are dual buffers. The MAX4201/MAX4204 have integrated 50 termination resistors, making them ideal for driving 50 transmission lines. The MAX4202/MAX4205 include 75 backtermination resistors for driving 75 transmission lines. The MAX4200/MAX4203 have no internal termination resistors. The MAX4200-MAX4205 use a proprietary architecture to achieve up to 780MHz -3dB bandwidth, 280MHz 0.1dB gain flatness, 4200V/s slew rate, and 90mA output current drive capability. They operate from 5V supplies and draw only 2.2mA of quiescent current. These features, along with low-noise performance, make these buffers suitable for driving high-speed analog-to-digital converter (ADC) inputs or for data-communications applications.

The MAX4200/MAX4203 are single/dual buffers with up to 660MHz bandwidth, 230MHz 0.1dB gain flatness, and a 4200V/s slew rate. The MAX4201/ MAX4204 single/dual buffers with integrated 50 output termination resistors, up to 780MHz bandwidth, 280MHz gain flatness, and a 4200V/s slew rate, are ideally suited for driving high-speed signals over 50 cables. The MAX4202/MAX4205 provide bandwidths up to 720MHz, 230MHz gain flatness, 4200V/s slew rate, and integrated 75 output termination resistors for driving 75 cables. With an open-loop gain that is slightly less than +1V/V, these devices do not have to be compensated with the internal dominant pole (and its associated phase shift) that is present in voltage-feedback devices. This feature allows the MAX4200-MAX4205 to achieve a nearly constant group delay time of 405ps over their full frequency range, making them well suited for a variety of RF and IF signal-processing applications. These buffers operate with 5V supplies and consume only 2.2mA of quiescent supply current per buffer while providing up to 90mA of output current drive capability. 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. Input Impedance The MAX4200-MAX4205 input impedance looks like a 500k resistor in parallel with a 2pF capacitor. Since these devices operate without negative feedback, there is no loop gain to transform the input impedance upward, as in closed-loop buffers. As a consequence, the input impedance is directly related to the output impedance. If the output load impedance decreases, the input impedance also decreases. Inductive input sources (such as an unterminated cable) may react with the input capacitance and produce some peaking in the buffer's frequency response. This effect can usually be minimized by using a properly terminated transmission line at the buffer input, as shown in Figure 1. 50 COAX R T* SOURCE RL 50 MAX42_ _ Applications Information Power Supplies The MAX4200-MAX4205 operate with dual supplies from 4V to 5.5V. Both VCC and VEE should be bypassed to the ground plane with a 0.1F capacitor located as close to the device pin as possible. Layout Techniques 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 6GHz. 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: Do not use wire-wrap boards, because they are too inductive. Do not use IC sockets, because they increase parasitic capacitance and inductance. Use surface-mount instead of through-hole components for better high-frequency performance. www.maximintegrated.com *MAX4201/4202/4204/4205 ONLY Figure 1. Using a Properly Terminated Input Source Output Current and Gain Sensitivity The absence of negative feedback means that open-loop buffers have no loop gain to reduce their effective output impedance. As a result, open-loop devices usually suffer from decreasing gain as the output current is decreased. The MAX4200-MAX4205 include local feedback around the buffer's class-AB output stage to ensure low output impedance and reduce gain sensitivity to load variations. This feedback also produces demand-driven current bias to the output transistors for 90mA (MAX4200/MAX4203) drive capability that is relatively independent of the output voltage (see Typical Operating Characteristics). Maxim Integrated 9 MAX4200-MAX4205 Ultra-High-Speed, Low-Noise, Low-Power, SOT23 Open-Loop Buffers Output Capacitive Loading and Stability The MAX4200-MAX4205 provide maximum AC performance with no load capacitance. This is the case when the load is a properly terminated transmission line. However, these devices are designed to drive any load capacitance without oscillating, but with reduced AC performance. Since the MAX4200-MAX4205 operate in an openloop configuration, there is no negative feedback to be transformed into positive feedback through phase shift introduced by a capacitive load. Therefore, these devices will not oscillate with capacitive loading, unlike similar buffers operating in a closed-loop configuration. However, a capacitive load reacting with the buffer's output impedance can still affect circuit performance. A capacitive load will form a lowpass filter with the buffer's output resistance, thereby limiting system bandwidth. With higher capacitive loads, bandwidth is dominated by the RC network formed by RT and CL; the bandwidth of the buffer itself is much higher. Also note that the isolation resistor forms a divider that decreases the voltage delivered to the load. Another concern when driving capacitive loads results from the amplifier's output impedance, which looks inductive at high frequency. This inductance forms an L-C resonant circuit with the capacitive load and causes peaking in the buffer's frequency response. www.maximintegrated.com Figure 2 shows the frequency response of the MAX4200/ MAX4203 under different capacitive loads. To settle out some of the peaking, the output requires an isolation resistor like the one shown in Figure 3. Figure 4 is a plot of the MAX4200/MAX4203 frequency response with capacitive loading and a 10 isolation resistor. In many applications, the output termination resistors included in the MAX4201/MAX4202/ MAX4204/MAX4205 will serve this purpose, reducing component count and board space. Figure 5 shows the MAX4201/MAX4202/ MAX4204/MAX4205 frequency response with capacitive loads of 47pF, 68pF, and 120pF. Coaxial Cable Drivers 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. The MAX4201/MAX4204, with their integrated 50 output termination resistors, are ideal for driving 50 cables. The MAX4202/MAX4205 include integrated 75 termination resistors for driving 75 cables. Note that the output termination resistor forms a voltage divider with the load resistance, thereby decreasing the amplitude of the signal at the receiving end of the cable by one half (see the Typical Application Circuit).
