Low-Power, +3V/+5V, 400MHz Single-Supply Op Amps with Rail-to-Rail Outputs
General Description
The MAX4414-MAX4419 operational amplifiers combine high-speed performance, low distortion, and ultralow supply current. Consuming just 1.6mA of supply current per amplifier, these devices operate from a single +2.7V to +5.5V supply, have Rail-to-Rail(R) outputs, and exhibit a common-mode input voltage range that extends from 100mV below ground to within 1.5V of the positive supply rail. The MAX4414/MAX4416/MAX4418 single/dual/quad op amps are unity-gain stable and achieve a 400MHz -3dB bandwidth with a 200V/s slew rate. The MAX4415/ MAX4417/MAX4419 single/dual/quad op amps are compensated for closed-loop gains of +5V/V or greater and achieve a 150MHz -3dB bandwidth with a 470V/s slew rate. The combination of high-speed, ultra-low power, and low-distortion makes the MAX4414- MAX4419 ideal for low-power/low-voltage, high-speed portable systems such as video, communications, and instrumentation. The MAX4414/MAX4415 single and MAX4416/ MAX4417 dual amplifiers are available in space-saving 8-pin MAX and SO packages, while the MAX4418/ MAX4419 quad amplifiers are available in a 14-pin TSSOP package. o Ultra-Low 1.6mA Supply Current o Single +3V/+5V Operation o High Speed 400MHz -3dB Bandwidth (MAX4414/MAX4416/MAX4418) 200V/s Slew Rate (MAX4414/MAX4416/MAX4418) 150MHz -3dB Bandwidth (MAX4415/MAX4417/MAX4419) 470V/s Slew Rate (MAX4415/MAX4417/MAX4419) o Rail-to-Rail Outputs o Input Common-Mode Range Extends Beyond VEE o Low Differential Gain/Phase: 0.03%/0.15 o Low Distortion at 5MHz (MAX4414/MAX4416/MAX4418) -93dBc SFDR 0.003% Total Harmonic Distortion o Low Cost

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.

MAX4414-MAX4419
_______________Detailed Description
The MAX4414-MAX4419 single-supply, rail-to-rail, voltage-feedback amplifiers achieve high slew rates and bandwidths, while consuming only 1.6mA of supply current per amplifier. 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. Internal feedback around the output stage ensures low open-loop output impedance, reducing gain sensitivity to load variations. This feedback also produces demand-driven current bias to the output transistors.
input can swing 3.6Vp-p, and the output can swing 4.6Vp-p with minimal distortion.
Output Capacitive Loading and Stability
The MAX4414-MAX4419 are optimized for AC performance. They are not designed to drive highly reactive loads. Such loads decrease phase margin and may produce excessive ringing and oscillation. The use of an isolation resistor eliminates this problem (Figure 1). Figure 2 is a graph of the Optimal Isolation Resistor (RISO) vs. Capacitive Load. The Small-Signal Gain vs. Frequency with Capacitive Load and No Isolation Resistor graph in the Typical Operating Characteristics 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 20 to 30) 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. The Small-Signal Gain vs. Frequency with Capacitive Load and 22 Isolation Resistor graph shows the effect of a 22 isolation resistor on closed-loop response.

Rail-to-Rail Outputs, Ground-Sensing Input
The MAX4414-MAX4419 input common-mode range extends from (VEE - 0.1V) to (VCC - 1.5V) 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. The output swings to within 105mV of either power-supply rail with a 1k load. Input ground sensing and railto-rail output substantially increase the dynamic range. With a symmetric input in a single +5V application, the

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. Inverting and Noninverting Configurations Select the gain-setting feedback (RF) and input (RG) resistor values that best fit the 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 1.8pF of amplifier input capacitance and 1pF of PC board capacitance, causes a pole at 114MHz. Since this pole is within the amplifier bandwidth, it jeopardizes stability. Reducing the 1k resistors to 100 extends the pole frequency to 1.14GHz, but could limit output swing by adding 200 in parallel with the amplifier's load resistor. Note: For high gain applications where output offset voltage is a consideration, choose RS to be equal to the parallel combination of RF and RG (Figures 3a and 3b): RS = RF x RG RF + RG

___________Applications Information
Choosing Resistor Values
Unity-Gain Configuration The MAX4414/MAX4416/MAX4418 are internally compensated for unity gain. When configured for unity gain, the devices require a 24 feedback resistor (RF). This resistor improves AC response by reducing the Q of the parallel LC circuit formed by the parasitic feedback capacitance and inductance.

Maxim recommends using microstrip and stripline techniques to obtain full bandwidth. Design the PC board for a frequency greater than 1GHz to prevent amplifier performance degradation due to board parasitics. Avoid large parasitic capacitances at inputs and outputs. Whether or not a constant-impedance board is used, observe the following guidelines: * Do not use wire-wrap boards due to their high inductance. * Do not use IC sockets because of the increased parasitic capacitance and inductance.
ADC Input Buffer
Input buffer amplifiers can be a source of significant errors in high-speed ADC applications. The input buffer is usually required to rapidly charge and discharge the ADC's input, which is often capacitive (see Output Capacitive Loading and Stability). In addition, since a high-speed ADC's input impedance often changes very rapidly during the conversion cycle, measurement accuracy must be maintained using an amplifier with very low output impedance at high frequencies. The combination of high speed, fast slew rate, low noise, and a low and stable distortion over load make the MAX4414-MAX4419 ideally suited for use as buffer amplifiers in high-speed ADC applications.
* 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.
Layout and Power-Supply Bypassing
These amplifiers operate from a single +2.7V to +5.5V power supply. Bypass V CC to ground with a 0.1F capacitor as close to the pin as possible.
