General Description

The MAX4389/MAX4390/MAX4392–MAX4396 family of

op amps are unity-gain stable devices that combine high-

speed performance, rail-to-rail outputs, and disable mode.

These devices are targeted for applications where an

input or an output is exposed to the outside world, such

as video and communications.

The MAX4389/MAX4390/MAX4392–MAX4396 operate

from a single 4.5V to 11V supply or from dual ±2.25V to

±5.5V supplies. The common-mode input voltage range

extends to the negative power-supply rail (ground in

single-supply applications). The MAX4389/MAX4390/

MAX4392–MAX4396 consume only 5.5mA of quiescent

supply current per amplifier while achieving a 85MHz

-3dB bandwidth, 27MHz 0.1dB gain flatness, and a

500V/μs slew rate. Disable mode sets the outputs to high

impedance while consuming only 450μA of current.

The MAX4389 single, MAX4393 dual, MAX4394 triple,

and MAX4396 quad include disable capabilities. The

MAX4389 and MAX4390 are available in ultra-small, 6-pin

SC70 packages.
