DESCRIPTION

The TDA9556 is a triple-channel video amplifier designed in a 120V-high voltage technology and able to drive in DC-coupling mode the 3 cathodes of a CRT monitor. The TDA9556 supports PICTURE BOOST applications where video amplitude up to 60V or above is required, ensuring a maximum quality of the still pictures or moving video. Perfecly matched with the TDA9210 and TDA9211 ST preamplifiers, it provides a highly performant and very cost effective video system.
