High-Speed, Single-Supply, Gain of 2,
Closed-Loop, Rail-to-Rail Buffers with Enable
_________________General Description
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 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
