_______________General Description

The MAX4108/MAX4109/MAX4308/MAX4309 op amps

combine ultra-high-speed performance with ultra-low-

distortion operation. The MAX4108 is compensated for

unity-gain stability; the MAX4109, MAX4308, and

MAX4309 are compensated for minimum closed-loop

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

= 100

Ω), making these amplifiers ideal for high-perfor-

mance RF signal processing.

These high-speed op amps feature a wide output volt-

age swing and a high-current output-drive capability of

90mA.
