MAX4389/MAX4390/
MAX4392–MAX4396
Ultra-Small, Low-Cost, 85MHz Op Amps with
Rail-to-Rail Outputs and Disable
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.
