Product specification
Video processor with automatic cut-off
and white level control
TDA4680
CHARACTERISTICS
All voltages are measured in test circuit of Fig.10 with respect to GND (pin 9); V
P
= 8.0 V; T
amb
= 25
°
C; nominal signal
amplitudes (black-to-white) at output pins 24, 22 and 20; nominal settings of brightness, contrast, saturation and white
level control; without beam current or peak drive limiting; unless otherwise specified.
