DESCRIPTION
The TDA9203A is a digitaly controlled wideband
video preamplifier intended for use in mid range
color monitor. All controls and adjustments are
digitaly performed thanks to I
trast, brightness and DC output level of RGB sig-
nals are common to the 3 channels and drive
adjustment is separate for each channel.Three I
gain controlled OSD inputs can be switched with
RGB signals using fast blanking command. Clamp-
ing of RGB signals is performed thanks to a flexible
integrated system. The white balance adjustment
is effective on brightness, video and OSD signals.
The TDA9203A works for application using AC or
DC coupled CRT driver.
The ABL input provides a 12dB Max. attenuation
on the current contrast value according average
beam limitation voltage.
Because of its features and due to component
saving the TDA9203A leads to a very performant
and cost effective application.
