General Description

The MAX4450 single and MAX4451 dual op amps are

unity-gain-stable devices that combine high-speed per-

formance 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 quies-

cent supply current per op amp while achieving a

210MHz -3dB bandwidth and a 485V/µs slew rate. Both

devices are an excellent solution in low-power/low-

voltage 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 space-

saving 8-pin SOT23 and SO packages.
