Datasheet
The MAX4350 single and MAX4351 dual op amps are
unity-gain-stable devices that combine high-speed per-
formance with rail-to-rail outputs. Both devices operate
from dual ±5V supplies. The common-mode input volt-
age range extends to the negative power-supply rail.
The MAX4350/MAX4351 require only 6.9mA of quies-
cent supply current per op amp while achieving a
210MHz -3dB bandwidth and a 485V/µs slew rate. Both
devices are excellent solutions in low-power systems
that require wide bandwidth, such as video, communi-
cations, and instrumentation.
The MAX4350 is available in an ultra-small 5-pin SC70
package and the MAX4351 is available in a space-
saving 8-pin SOT23 package.
