amplifier’s accuracy and stability. In general, use sur-
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
0.1µF surface-mount ceramic capacitors between each
supply pin 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.
MAX4430–MAX4433 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).
