M52732SP
3-CHANNEL VIDEO AMPLIFICATION
DESCRIPTION
The M52732SP is a semiconductor integrated circuit that has 3-
channels 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
• It realize low power dissipation so that 3-channels are built in.
(VCC=12V, ICC=63mA)
• Input..........................................................................0.7VP-P (typ.)
Output.....................................................................4.5VP-P (max.)
Frequency band.................................................75MHz (at 3VP-P)
• To adjust contrast, two types of controls are provided, main and
sub.
The main controls adjusts 3-channels of contrast concurrently.
The sub contrast controls adjusts either channel independentry.
APPLICATION
Display monitor
RECOMMENDED OPERATING CONDITION
Supply voltage range....................................................11.5 to 12.5V
