• Manufacturer Part Number: max9503getet
• Description: Max9503 Directdrive Video Amplifier With Reconstruction Filter
• Manufacturer: Maxim Integrated Products, Inc.

The MAX9503 operates from a 2.7V to 3.6V single sup-
ply and requires proper layout and bypassing. For the
best performance, place the components as close to
the device as possible.
Proper grounding improves performance and prevents
any switching noise from coupling into the video signal.
Connect GND and SGND together at a single point on
the PC board. Route all traces that carry switching tran-

impedance ground available. Route CPGND and all
traces carrying switching transients away from SGND,
