TDA8153

TDA8153 RGB VIDEO OUTPUT AMPLIFIER . . . . . . THREE INDEPENDENT VIDEO AMPLIFIERS WITH TYPICAL SR > 1000V/µs CRT-CATHODE SENSING OUTPUT FOR SEQUENTIAL SAMPLING INTERNAL G1 VOLTAGE GENERATOR CATHODE SHORT CIRCUIT PROTECTION FLASHOVER PROTECTION OF THE OUTPUT STAGES COMPENSATES POSITIVE AND NEGATIVE TUBE LEAKAGES DESCRIPTION Realized with a high voltage bipolar technology,the TDA8153 is a monolithic RGB video output stage for TV color applications. It drives the CRT cathodes directly and offers a video bandwidth compatible with CCIR standards. In addition to three independent video amplifiers, the device features an internal generator for the first grid voltage, flashover protection, cathode short circuit protection and a common cut-off sensing output for use in sequential sampling applications. The TDA8153 is supplied in a 15 lead Multiwatt plastic power package.
