_______________General Description

The MAX4014/MAX4017/MAX4019/MAX4022 are preci-

sion, closed-loop, gain of +2 (or -1) buffers featuring

high slew rates, high output current drive, and low dif-

ferential gain and phase errors. These single-supply

devices operate from +3.15V to +11V, or from ±1.575V

to ±5.5V dual supplies. The input voltage range extends

100mV beyond the negative supply rail and the outputs

swing Rail-to-Rail

These devices require only 5.5mA of quiescent supply

current while achieving a 200MHz -3dB bandwidth and

a 600V/µs slew rate. In addition, the MAX4019 has a

disable feature that reduces the supply current to

400µA. Input voltage noise for these parts is only

10nV/√Hz and input current noise is only 1.3pA/√Hz.

This buffer family is ideal for low-power/low-voltage

applications that require wide bandwidth, such as

video, communications, and instrumentation systems.

For space-sensitive applications, the MAX4014 comes

in a tiny 5-pin SOT23 package.
