Applications Information
Output Load Capacitor
The output load capacitor must have a low ESR value
(50m or lower) and it must be placed as close as pos-
sible to the OUT pin to ensure buffer stability (see
Figure 2). Ceramic capacitors are an excellent choice.
Power Supplies and Bypass Capacitors
The MAX9550/MAX9551/MAX9552 operate from a 6V to
20V single supply, or from ±3V to ±10V dual supplies.
Proper supply bypassing ensures stability while driving
high transient loads. The MAX9550/MAX9551/MAX9552
require minimum 4.7F (C1) and 0.1F (C2) power-sup-
ply bypass capacitors placed as close as possible to
the power-supply pin (VDD). See Figure 2. For dual-
supply operation, use 4.7F and 0.1F bypass capaci-
tors on both supplies (VDD and GND) with each
capacitor placed as close as possible to the VDD and
GND pins.
Layout and Grounding
The exposed paddle on the MAX and TSSOP pack-
ages provides a low thermal resistance for heat dissi-
pation. Solder the exposed paddle to a ground plane
for best results. Do not route traces under these pack-
ages. For dual-supply operation, the exposed paddle
(EP) must be electrically connected to the negative
supply or it can be left unconnected.
