face-mount components since they have shorter bodies

and lower parasitic reactance. This will result in

improved performance over through-hole components.

The bypass capacitors should include 1nF and/or

and the ground plane, located as close to the package

as possible. Place a 10µF tantalum capacitor at the

power supply’s point of entry to the PC board to ensure

the integrity of the incoming supplies. Input termination

resistors and output back-termination resistors, if used,

should be surface-mount types and should be placed

as close to the IC pins as possible.

Driving Capacitive Loads

The MAX4434–MAX4437 can drive capacitive loads.

However, excessive capacitive loads may cause ring-

ing or instability at the output as phase margin is

reduced. Adding a small isolation resistor in series with

the output capacitive load helps reduce the ringing but

slightly increases gain error (see Typical Operating

Characteristics and Figure 3).
