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 Railto- Rail outputs. The MAX4018 has a disable feature that reduces power-supply current to 400ìA 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/ìs slew rate. These parts are an excellent solution in low-power/low-voltage systems that require wide bandwidth, such as video, communications, and instrumentation. 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 ìMAX® and SO packages. The MAX4018/MAX4020 are available in a space-saving 16-pin QSOP, as well as a 14-pin SO.

MAX4012/MAX4016/MAX4018/MAX4020 Detailed Description The MAX4012/MAX4016/MAX4018/MAX4020 are single- supply, rail-to-rail, voltage-feedback amplifiers that employ current-feedback techniques to achieve 600V/ìs slew rates and 200MHz bandwidths. Excellent harmonic distortion and differential gain/phase performance make these amplifiers an ideal choice for a wide variety of video and RF signal-processing applications. The output voltage swing comes to within 50mV of each supply rail. Local feedback around the output stage assures low open-loop output impedance to reduce gain sensitivity to...
