Ultra-Small, Low-Cost, 210MHz, Dual-Supply
Op Amps with Rail-to-Rail Outputs
General Description
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.

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.
