+3V/+5V, 250MHz, SOT23 ADC Buffer Amplifiers

with High-Speed Disable

General Description

The 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 鹵1.425V to 鹵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/碌s 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 碌MAX and 8-pin SO packages,

while the MAX4288/MAX4388 come in 10-pin 碌MAX and

14-pin SO packages.
