DirectDrive Video Amplifier with
Short-to-Battery Protection
The MAX9532 operates from a 3V to 3.6V single supply
and requires proper layout and bypassing. For the best
performance, place the components as close as possi-
ble to the device.
Proper grounding improves performance and prevents
any switching noise from coupling into the video signal.
