+3V/+5V / 250MHz / SOT23 ADC Buffer Amplifiers with High-Speed Disable
General DescriptionThe MAX4285/MAX4286 single and MAX4287/MAX4288/
MAX4387/MAX4388 dual ADC buffer amplifiers feature
high-speed performance and single +3V supply opera-
tion. The MAX4285/MAX4286/MAX4288 and MAX4388
offer a disable feature that reduces power-supply current
and places the outputs in a high-impedance state. All six
devices operate from a +2.85V to +6.5V single supply or
from ±1.425V to ±3.25V dual supplies. The common-
mode input voltage range extends to the negative power-
supply rail (ground in single-supply applications).
These devices require 20mA of quiescent supply current
per amplifier while achieving a 250MHz -3dB bandwidth
and a 350V/µs slew rate. The combination of an 8ns (to
0.1%) settling time, 88dBc (f = 5MHz) of SFDR, and up to
100mA output drive makes these amplifiers ideal for high-
speed ADC drivers for communications and instrumenta-
tion applications. In addition, when disabled, their high
output impedance makes them ideal for multiplexing
applications.
The MAX4285/MAX4286 are available in space-saving
6-pin SOT23 and 8-pin SO packages. The MAX4287/
MAX4387 come in 8-pin µMAX and 8-pin SO packages,
while the MAX4288/MAX4388 come in 10-pin µMAX and
14-pin SO packages.
