3-CHANNEL VIDEO AMPLIFICA TION
DESCRIPTION
The M52732SP is a semiconductor integrated circuit that has 3channels of built-in amplifiers in the broad-band video amplifier
having a 75MHz band. Every channel is provided with a broad-band
amplifier, contrast control (main and sub), and brightness control. It
accordingly has an optimal configuration for use with high
resolution color display monitors.
FEATURES
