MAX4286

+3 V, +5 V at /250MHz, SOT23 ADC with high speed disable bufferingamplifier

description

The MAX4285/MAX4286 single and MAX4287/MAX4288/MAX4387/MAX4388 dual ADC buffer amplifiers feature high-speed performance and +3 V single-supply operation. The MAX4285/MAX4286/MAX4288, and MAX4388 provide a disable function to reduce supply current and place the output in a high-impedance state. All six devices operate from a single +2.85 V to +6.5 V supply or dual ±1.425 V to ±3.25 V supplies. The common-mode input voltage range extends to the negative rail (ground in single-supply applications).

These devices require a quiescent supply current of 20 mA per amplifier while achieving a -3dB bandwidth of 250MHz and a slew rate of 350V/μs. A combination of 8ns (0.1%), settling time, 88dBc SFDR (F = 5MHz), and up to 100mA output drive makes these amplifiers ideal for high speed ADC driver 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 are available in 8-pin μMAX and 8-pin SO packages, while the MAX4288/MAX4388 are available in 10-pin μMAX® and 14-pin SO packages.
