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.

ful attention to inputs and outputs to avoid large parasitic capacitance. Whether or not you use a constantimpedance board, observe the following design guidelines: • Don’t use wire-wrap boards; they are too inductive. • Don’t use IC sockets; they increase parasitic capacitance and inductance. • Use surface-mount instead of through-hole components for better high-frequency performance. • Use a PC board with at least two layers; it should be as free from voids as possible.
