Low-Cost, High-Speed, Single-Supply
Op Amps with Rail-to-Rail Outputs
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or at any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
