The MAX4030E/MAX4031E dual/triple, 5V operational
amplifiers achieve 115V/µs slew rates and 144MHz
bandwidths. High ±15kV ESD protection at video inputs
and outputs guards against unexpected discharge.
Excellent harmonic distortion and differential gain/
phase performance make these amplifiers an ideal
choice for a wide variety of video and RF signal-pro-
cessing applications.
The MAX4030E/MAX4031E input stage can sense com-
mon-mode voltages from ground to within 2.25V of the
positive supply.
The MAX4030E/MAX4031E rail-to-rail outputs can
swing to within 100mV of each supply because local
feedback around the output stage ensures low open-
loop output impedance, reducing gain sensitivity to
load variations.
The MAX4031E offers individual shutdown control for
each amplifier. Drive SHDN_ low to shut down the
amplifier. In shutdown, the amplifier output impedance
is high impedance.

AC performance. This resistor improves AC response by
reducing the Q of the parallel LC circuit formed by the
parasitic feedback capacitance and lead inductance.
The MAX4030E/MAX4031E are low-power, voltage-
feedback amplifiers featuring bandwidths up to 40MHz
and 0.1dB gain flatness to 9MHz. They are designed to
minimize differential-gain error and differential-phase
error to 0.2% and 0.2°, respectively. They have a 40ns
settling time to 0.1%, 110V/µs slew rates, and output-
current-drive capability of up to 50mA, making them
ideal for driving video loads.
Select the feedback (R

resistor values increase voltage noise and interact with
