MAXIM Manuals (Industrial)

The MAX4285/MAX4286/MAX4287/MAX4288/MAX4387/MAX4388 is a high-performance ADC buffer amplifier operating from a single +3V supply. The device offers 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.

These characteristics make these op amps ideal for driving modern high-speed 14- and 16-bit analog-to-digital converters (ADCs). These high-speed op amps feature wide output voltage swings capable of driving ADCs with ≥4V input dynamic range and a high current output drive up to 60mA. Using a voltage feedback architecture, the MAX4430– MAX4433 meet the requirements of many applications that previously depended on current feedback amplifiers. The MAX4430/MAX4431 are available in a space-saving 5-pin SOT23 package, and the MAX4432/MAX4433 are available in an 8-pin µMAX package.

The MAX6010 is a precision, low-noise, low-dropout, micropower voltage reference in a SOT23 package. This three-terminal voltage reference operates with an input voltage from 3.2V to 5.5V, and outputs 3V.

The MAX6010 has initial accuracies of 0.2% (A grade) and 0.4% (B grade) and a temperature drift of 50ppm/°C (max). The low-dropout voltage and the ultra-low supply current over the full voltage range make this device ideal for portable and battery-operated applications.
