    • -72dBc SFDR
    • -71dB Total Harmonic Distortion
  • High Output Drive: ±120mA

  • Space-Saving SOT23, µMAX®, or QSOP Packages

The MAX4214/MAX4215/MAX4217/MAX4219/MAX4222 are precision, closed-loop, gain of +2 (or -1) buffers featuring high slew rates, high output current drive, and low differential gain and phase error. They operate with a single 3.15V to 11V supply or with ±1.575V to ±5.5V dual supplies. The input common-mode voltage range extends 100mV beyond the negative power-supply rail, and the output swings Rail-to-Rail.

These devices require only 5.5mA of quiescent supply current while achieving a 230MHz -3dB bandwidth and a 600V/µs slew rate. In addition, the MAX4215/MAX4219 have a disable feature that reduces the supply current to 400µA per buffer. Input voltage noise is only 10nV per root-Hz , and input current noise is only 1.3pA per root-Hz. This buffer family is ideal for low-power/low-voltage applications requiring wide bandwidth, such as video, communications, and instrumentation systems. For space-sensitive applications, the MAX4214 comes in a miniature 5-pin SOT23 package.
