MAX4389/MAX4390/ MAX4392-MAX4396 Ultra-Small, Low-Cost, 85MHz Op Amps with Rail-to-Rail Outputs and Disable General Description The MAX4389/MAX4390/MAX4392-MAX4396 family of op amps are unity-gain stable devices that combine highspeed 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. The MAX4389/MAX4390/MAX4392-MAX4396 operate from a single 4.5V to 11V supply or from dual 2.25V to 5.5V supplies. The common-mode input voltage range extends to the negative power-supply rail (ground in single-supply applications). The MAX4389/MAX4390/ MAX4392-MAX4396 consume only 5.5mA of quiescent supply current per amplifier while achieving a 85MHz -3dB bandwidth, 27MHz 0.1dB gain flatness, and a 500V/s slew rate. Disable mode sets the outputs to high impedance while consuming only 450A 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.

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.

Connect to VCC to enable. 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 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. Maxim Integrated 11 MAX4389/MAX4390/ MAX4392-MAX4396 Ultra-Small, Low-Cost, 85MHz Op Amps with Rail-to-Rail Outputs and Disable Video Line Driver The MAX4389/MAX4390/MAX4392-MAX4396 are lowpower, voltage-feedback amplifiers featuring large-signal (2VP-P) bandwidths of 90MHz and 0.1dB large-signal 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/s slew rates, and outputcurrent-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 PCB capacitance. This can generate undesirable poles and zeros and decrease bandwidth or cause oscillations. For example, a noninverting gain-oftwo configuration (RF = RG) using 2k resistors, combined with 1pF of amplifier input capacitance and 1pF of PCB capacitance, causes a pole at 79.6MHz. Since this pole is within the amplifier bandwidth, it jeopardizes stability. Reducing the 2k 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). RF RG VOUT MAX43_ _ VIN VOUT = [1 + (RF / RG)] VIN 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 0.1F capacitor as close to the pin as possible. Maxim recommends using microstrip and stripline techniques to obtain full bandwidth. To ensure that the PCB 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 PCB 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 95k. 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 Figure 1a. Noninverting Gain Configuration VIN RG RF MAX43_ _ VOUT VOUT = -(RF / RG) VIN Figure 1b. Inverting Gain Configuration www.maximintegrated.com 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 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.
