Closed-Loop, Rail-to-Rail Buffers with Enable
_________________General Description
____________________________Features
ꢀ Internal Precision Resistors for Closed-Loop
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®.

(MAX4219/MAX4222)
600V/µs Slew Rate
ꢀ Single 3.3V/5.0V Operation
ꢀ Outputs Swing 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 sup-
ply current to 400µA per buffer. Input voltage noise is
only 10nV/√Hz, and input current noise is only
1.3pA/√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.
