_______________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.
