_______________General Description

The MAX4108/MAX4109/MAX4308/MAX4309 op amps
combine ultra-high-speed performance with ultra-low­distortion operation. The MAX4108 is compensated for
unity-gain stability; the MAX4109, MAX4308, and
MAX4309 are compensated for minimum closed-loop
gains (A

VCL

) of 2V/V, 5V/V, and 10V/V, respectively.

The MAX4108 delivers a 400MHz unity-gain bandwidth
with a 1200V/µs slew rate. An ultra-low-distortion design
provides an unprecedented spurious-free dynamic
range of -93dBc (MAX4108) at 5MHz (V

OUT

= 2Vp-p, R

L

= 100Ω), making these amplifiers ideal for high-perfor­mance RF signal processing.

These high-speed op amps feature a wide output volt­age swing and a high-current output-drive capability of
90mA.

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.
