General Description

The MAX4385E/MAX4386E op amps are unity-gain sta-

ble devices that 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 communica-

tions, 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 MAX4385E/MAX4386E operate from a single 5V

supply with a common-mode input voltage range that

extends beyond V

. The MAX4385E/MAX4386E con-

sume only 5.5mA of quiescent supply current per

amplifier while achieving a 230MHz -3dB bandwidth,

30MHz 0.1dB gain flatness and a 450V/µs slew rate.

MAX4385E/MAX4386E Low-Cost, 230MHz, Single/Quad Op Amps with Rail-to-Rail Outputs and ±15kV ESD Protection ESD Protection As with all Maxim devices, ESD protection structures are incorporated on all pins to protect against ESD encountered during handling and assembly. Input and output pins of the MAX4385E/MAX4386E have extra protection against static electricity.
