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 -3dBband width and a600V/µs slew rate. These parts are an excellent solution 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 applica-tions.
The MAX4012 comes in a miniature 5-pin SOT23 package, while the MAX4016 comes in 8-pin µMAX and SOpackages. The MAX4018/MAX4020 are available in a space-saving 16-pin QSOP, as well as a 14-pin SO.
