MAXIM MAX4450, MAX4451 Technical data

General Description

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/µs 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 space­saving 8-pin SOT23 and SO packages.

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.
