MAX9650/MAX9651
Applications Information
Output Load
The MAX9650/MAX9651 are designed to drive capaci-
tive loads. A small value of series resistance improves
the performance of the device to ensure stability and
fast settling with very large or very small capacitive
loads. In many cases, this resistance is already present
due to connection resistance in the wiring and no addi-
tional physical resistor is necessary. For minimum
series resistance required for stability with capacitive
loading, see Figure 2.
Power Supplies and Bypass Capacitors
The MAX9650/MAX9651 operate from a 6V to 20V sin-
gle supply or from ±4.5V to ±10V dual supplies. Proper
supply bypassing ensures stability while driving high
transient loads. The MAX9650/MAX9651 require a mini-
mum 10F (C1) and 0.1F (C2) power-supply bypass
capacitors placed as close as possible to the power-
supply pin (VDD). See Figure 3. For dual-supply opera-
tion, use 10F and 0.1F bypass capacitors on both
supplies (VDD and GND) with each capacitor placed as
close as possible to VDD and GND.
Layout and Grounding
The exposed pad on the MAX and TDFN packages
provide a low thermal resistance for heat dissipation.
Solder the exposed pad to a ground plane for best
thermal performance. Do not route traces under these
packages. For dual-supply operation, the exposed pad
(EP) can be electrically connected to the negative sup-
ply or it can be left unconnected.
