General Description

The MAX4030E/MAX4031E unity-gain stable op amps

combine high-speed performance, rail-to-rail outputs,

and ±15kV ESD protection. Targeted for applications

where an input or an output is exposed to the outside

world, such as video and communications, these

devices are compliant with International ESD

Standards: ±15kV IEC 1000-4-2 Air-Gap Discharge,

±8kV IEC 1000-4-2 Contact Discharge, and the ±15kV

Human Body Model.

The MAX4030E/MAX4031E operate from a single 5V

supply and consume only 12mA of quiescent supply

current per amplifier while achieving a 144MHz -3dB

bandwidth, 20MHz 0.1dB gain flatness, and a 115V/µs

slew rate. The MAX4031E provides individual shutdown

control for each of the amplifiers.

The dual MAX4030E is available in 8-pin µMAX

and SO

packages, and the triple MAX4031E is available in 14-pin

TSSOP and SO packages. All devices are specified over

the -40°C to +85°C extended temperature range.
