The MAX4450 single and MAX4451 dual op amps are unity-gain-stable devices that combine high-speed performance with Rail-to-Rail outputs. Both devices operate from a +4.5V to +11V single supply or from 2.25V to 5.5V dual supplies. The common-mode input voltage range extends beyond the negative power-supply rail (ground in single-supply applications). The MAX4450/MAX4451 require only 6.5mA of quiescent supply current per op amp while achieving a 210MHz -3dB bandwidth and a 485V/s slew rate. Both devices are an excellent solution in low-power/lowvoltage systems that require wide bandwidth, such as video, communications, and instrumentation. The MAX4450 is available in the ultra-small 5-pin SC70 package, while the MAX4451 is available in a spacesaving 8-pin SOT23.
