DESCRIPTION
The TDA9206 is a digitaly controlled wideband
video preamplifier intended for use in high resolu-
tion color monitor. All controls and adjustments are
digitaly performed thanks to I2C serial bus. Con-
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 I2C
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 TDA9206works for application usingAC or DC
coupled CRT driver.
Because of its features and due to component
saving the TDA9206 leads to a very performantand
cost effective application.
