General Description

The MAX4012 single, MAX4016 dual, MAX4018 triple,

and MAX4020 quad op amps are unity-gain-stable

devices that combine high-speed performance with Rail-

to-Rail outputs. The MAX4018 has a disable feature that

reduces power-supply current to 400µA and places its

outputs into a high-impedance state. These devices

operate from a 3.3V to 10V single supply or from ±1.65V

to ±5V dual supplies. The common-mode input voltage

range extends beyond the negative power-supply rail

(ground in single-supply applications).

These devices require only 5.5mA of quiescent supply

current while achieving a 200MHz -3dB bandwidth and

a 600V/µs slew rate. These parts are an excellent solu-

tion in low-power/low-voltage systems that require wide

bandwidth, such as video, communications, and instru-

mentation. In addition, when disabled, their high-output

impedance makes them ideal for multiplexing

applications.

The MAX4012 comes in a miniature 5-pin SOT23 and 8-

pin SO package, while the MAX4016 comes in 8-pin

µMAX

and SO packages. The MAX4018/MAX4020 are

available in a space-saving 16-pin QSOP, as well as a

14-pin SO.
