MAX4285, MAX4286, MAX4287, MAX4288, MAX4387, MAX4388 +3V/+5V, 250MHz, SOT23 ADC Buffer Amplifiers With High-Speed Disable

The MAX4285 MAX4286 single and MAX4287 MAX4288 MAX4387 MAX4388 dual ADC Buffer Amplifiers feature high-speed performance and single +3V supply operation. 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/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 instrumentation 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 MAX and 8-pin SO packages, while the MAX4288 MAX4388 come in 10-pin MAX and 14-pin SO packages.
