MAX4388
Description
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 monmode input voltage range extends to the negative powersupply rail (ground in single-supply applications). These devices require 20m A of quiescent supply current per amplifier while achieving a 250MHz -3d B bandwidth and a 350V/µs slew rate. The bination of an 8ns (to 0.1%) settling time, 88d Bc (f = 5MHz) of SFDR, and up to 100m A output drive makes these amplifiers ideal for highspeed ADC drivers for munications and instrumentation applications. In addition, when disabled, their high output impedance makes them ideal for multiplexing applications. The MAX4285/MAX4286 are...
