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.
