9 / 12 page _______________Detailed Description The MAX4104/MAX4105/MAX4304/MAX4305 are ultra- high-speed, low-noise amplifiers featuring -3dB band- widths up to 880MHz, 0.1dB gain flatness up to 100MHz, and low differential gain and phase errors of 0.01% and 0.01°, respectively. These devices operate on dual power supplies ranging from ±3.5V to ±5.5V and require only 20mA of supply current. The MAX4104/MAX4304/MAX4105/MAX4305 are opti- mized for minimum closed-loop gains of +1V/V, +2V/V, +5V/V and +10V/V (respectively) with corresponding -3dB bandwidths of 880MHz, 730MHz, 430MHz, and 350MHz. Each device in this family features a low input voltage noise density of only 2.1nV/ √Hz (at 1MHz), an output current drive of ±70mA, and spurious-free dynamic range as low as -88dBc (5MHz, RL = 100Ω). ___________Applications Information Layout and Power-Supply Bypassing The MAX4104/MAX4105/MAX4304/MAX4305 have an extremely high bandwidth, and consequently require careful board layout, including the possible use of constant-impedance microstrip or stripline techniques. To realize the full AC performance of these high-speed amplifiers, pay careful attention to power-supply bypassing and board layout. The PC board should have at least two layers: a signal and power layer on one side, and a large, low-impedance ground plane on the other side. The ground plane should be as free of voids as possible. With multilayer boards, locate the ground plane on a layer that incorporates no signal or power traces. Regardless of whether or not a constant-impedance board is used, it is best to observe the following guide- lines when designing the board: 1) Do not use wire-wrapped boards (they are much too inductive) or breadboards (they are much too capacitive). 2) Do not use IC sockets. IC sockets increase reac- tances. 3) Keep signal lines as short and straight as possible. Do not make 90° turns; round all corners. 4) Observe high-frequency bypassing techniques to maintain the amplifier’s accuracy and stability. 5) Bear in mind that, in general, surface-mount compo- nents have shorter bodies and lower parasitic reac- tance, resulting in greatly improved high-frequency performance over through-hole components. The bypass capacitors should include 1nF and 0.1µF ceramic surface-mount capacitors between each sup- ply pin and the ground plane, located as close to the package as possible. Optionally, place a 10µF tantalum capacitor at the power supply pins’ point of entry to the PC board to ensure the integrity of incoming supplies. The power-supply trace should lead directly from the tantalum capacitor to the VCC and VEE pins. To mini- mize parasitic inductance, keep PC traces short and use surface-mount components. Input termination resistors and output back-termination resistors, if used, should be surface-mount types, and should be placed as close to the IC pins as possible. DC and Noise Errors The MAX4104/MAX4105/MAX4304/MAX4305 output offset voltage, VOUT (Figure 1), can be calculated with the following equation: VOUT = [VOS + (IB+ x RS) + (IB- x (RF || RG))] [1 + RF / RG] where: VOS = input offset voltage (in volts) 1 + RF/RG = amplifier closed-loop gain (dimensionless) IB+ = noninverting input bias current (in amps) IB- = inverting input bias current (in amps) RG = gain-setting resistor (in ohms) RF = feedback resistor (in ohms) RS = source resistor at noninverting input (in ohms) The following equation represents output noise density: e 1 R R i x R i x R R e n(OUT) F G n S 2 n F G 2 n 2 || = + ( ) + ( ) + 740MHz, Low-Noise, Low-Distortion Op Amps in SOT23-5 _______________________________________________________________________________________ 9 _____________________Pin Description SOT23-5 SO OUT VCC VEE IN+ IN- N.C.
