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 V_CC
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).
