_______________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/s slew rate. In addition, the MAX4019 has a
disable feature that reduces the supply current to
400A. 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.
