_______________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
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-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.
