TDA8303 Description
The TDA8303/TDA8303A bines all small signal functions (except the tuner) which are required for a monochrome television receiver. For a plete black and white receiver only the output stages for video, sound, horizontal and vertical deflection and a tuner have to be added. The TDA8303 is for applications with npn tuners and the TDA8303A for pnp tuners.
