TDA1771 is a monolithic integrated circuit intended for direct drive of a TV picture tube in Color and B & W television, as well as in Monitor and Data displays. It is a full performance and very efficient vertical deflection circuit.
The TDA1771 is a monolithic integrated circuit in a SIP10 plastic package designed for vertical deflection in color and B&W television picture tubes, monitors, and data displays. It integrates a ramp generator, buffer stage, power amplifier, flyback generator, internal reference voltage, and thermal protection.
The document lists absolute maximum ratings, thermal data, detailed electrical characteristics (supply voltage, output currents, reference voltages, gain, etc.), an example application circuit, and mechanical dimensions of the 10‑pin SIP package. Legal and licensing information for SGS‑THOMSON components is also included.
