MAX4106/MAX4107
_______________General Description
The MAX4106/MAX4107 op amps combine high-speed
performance with ultra-low-noise performance. The
MAX4106 is compensated for closed-loop gains of
5V/V, while the MAX4107 is stable in closed-loop gains
of 10V/V or greater.
The MAX4106/MAX4107 require only 15mA of supply
current while delivering a 350MHz or a 300MHz bandwidth, respectively. Voltage noise is an ultra-low
0.75nV/√Hz, while a low-distortion architecture provides
a spurious-free dynamic range (SFDR) of 63dB at
5MHz.
These high-speed op amps have a wide output voltage
swing of ±3.2V and a high current-drive capability of
80mA.

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.

_______________General Description
Choosing Resistor Values
The values of the gain-setting feedback and input resistors are important design considerations. Large resistor
values will increase voltage noise, and will interact with
the amplifier’s input and PC board capacitance to generate undesirable poles and zeros, which can decrease
bandwidth or cause oscillations. For example, a noninverting gain of +5 (MAX4106), using a 1kΩ feedback
resistor combined with 2pF of input capacitance and
0.5pF of board capacitance, will cause a feedback
pole at 318MHz. If this pole is within the anticipated
amplifier bandwidth, it will jeopardize stability.
Reducing the 1kΩ feedback resistor to 40Ω will extend
the pole frequency to 8GHz, but could limit output
swing by adding 50Ω in parallel with the amplifier’s
load. Clearly the selection of resistor values must be
tailored to the specific application.
The MAX4106/MAX4107 are optimized for AC performance. They are not designed to drive highly reactive
loads. Reactive loads will decrease phase margin and
may produce excessive ringing and oscillation. Figure
1a shows a circuit that eliminates this problem, and
Figure 1b is a graph of the optimal isolation resistor
(RS) vs. capacitive load. Figures 2a and 2b show how a
capacitive load causes excessive peaking of the amplifier’s bandwidth if the capacitive load is not isolated
(RS) from the amplifier. A small isolation resistor (usually 10Ω to 20Ω) placed before the reactive load prevents
ringing and oscillation. At higher capacitive loads, AC
performance will be controlled by the interaction of the
load capacitance and isolation resistor. Figures 3a and
3b show the effect of an isolation resistor on the
MAX4106/MAX4107 closed-loop response.
Coaxial cable and other transmission lines are easily
driven when terminated at both ends with their characteristic impedance. When driving back-terminated
transmission lines, the capacitance of the transmission
line is essentially eliminated.

RG
30Ω
The MAX4106/MAX4107 are ultra-low-noise, high-bandwidth op amps. The output noise voltage can be dominated by resistor thermal noise, so keep the feedback
and input resistors small. Setting the input resistor to
30Ω and choosing the feedback resistor to suit the gain
will provide excellent AC performance without significantly degrading noise performance.
