_______________General Description
The MAX4012 single, MAX4016 dual, MAX4018 triple,
and MAX4020 quad op amps are unity-gain-stable
devices that combine high-speed performance with
Rail-to-Rail
outputs. The MAX4018 has a disable fea-
ture that reduces power-supply current to 400A and
places its outputs into a high-impedance state. These
devices operate from a +3.3V to +10V single supply or
from 1.65V to 5V dual supplies. The common-mode
input voltage range extends beyond the negative
power-supply rail (ground in single-supply applica-
tions).
These devices require only 5.5mA of quiescent supply
current while achieving a 200MHz -3dB bandwidth and
a 600V/s slew rate. These parts are an excellent solu-
tion in low-power/low-voltage systems that require wide
bandwidth, such as video, communications, and instru-
mentation. In addition, when disabled, their high output
impedance makes them ideal for multiplexing applica-
tions.
The MAX4012 comes in a miniature 5-pin SOT23 pack-
age, while the MAX4016 comes in 8-pin MAX and SO
packages. The MAX4018/MAX4020 are available in a
space-saving 16-pin QSOP, as well as a 14-pin SO.
