_______________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 band-
width, 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.
