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 oper-
ate from a +4.5V to +11V single supply or from 2.25V
to 5.5V dual supplies. The common-mode input volt-
age 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/s 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 a space-
saving 8-pin SOT23.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or at any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
