♦ 500MHz Unity-Gain Bandwidth
♦ Optional Adjustable Gain
The MAX4100 evaluation kit (EV kit) simplifies evalua-
tion of the MAX4100 high-speed amplifier. The EV kit
circuit demonstrates the MAX4100 in the noninverting
unity-gain configuration. RF-style connectors (SMA)
and 75Ω terminating resistors are included for video
test equipment compatibility.
♦ Fully Assembled and Tested
______________Ord e rin g In fo rm a t io n
The EV kit comes with the MAX4100 installed. To evalu-
a te the MAX4101, s imp ly ord e r a fre e s a mp le
(MAX4101ESA), re p la c e the MAX4100 with the
MAX4101 on the EV b oa rd , a nd c ha ng e the g a in-
setting resistors for the desired gain. The minimum
closed-loop gain for the MAX4101 is +2V/V or -1V/V.
