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 dis-
able 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 sin-
gle-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.

Detailed Description
The MAX4389/MAX4390/MAX4392–MAX4396 are dual-
supply, rail-to-rail, voltage-feedback amplifiers that
employ current-feedback techniques to achieve
500V/µs slew rates and 85MHz bandwidths. Excellent
harmonic distortion and differential gain/phase perfor-
mance make these amplifiers an ideal choice for a wide
variety of video and RF signal-processing applications.
Applications Information
The output voltage swings to within 200mV of each
supply rail. Local feedback around the output stage
ensures low open-loop output impedance to reduce
gain sensitivity to load variations. The input stage per-
mits common-mode voltages to the negative supply
and to within 2.25V of the positive supply rail.
Choosing Resistor Values
Unity-Gain Configuration
The MAX4389/MAX4390/MAX4392–MAX4396 are inter-
nally compensated for unity gain. When configured for
unity gain, a 24Ω resistor (RF) in series with the feed-
back path optimizes AC performance. This resistor
improves AC response by reducing the Q of the paral-
lel LC circuit formed by the parasitic feedback capaci-
tance and inductance.
