TDA8303 - Small signal combination IC for black/white TV

📥 Download Datasheet

General Description

The TDA8303/TDA8303A combines all small signal functions (except the tuner) which are required for a monochrome television receiver.

For a complete 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.
