The STV9553 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 STV9553 supports PICTURE BOOST applications where video amplitude up to 50V or above is required, ensuring a maximum quality of the still pictures or moving video. Perfecly matched with the STV921x ST preamplifiers, it provides a highly performant and very cost effective video system.
The STV9553 is a three‑channel video amplifier designed for high‑voltage applications such as picture‑boost CRT monitors. It operates with a low supply voltage (≈12 V) and a high supply voltage up to 115 V, providing up to 80 V output dynamic range and a built‑in voltage gain of 20.
Key features include a typical rise and fall time of 12 ns, a bandwidth of 29 MHz, very low standby power consumption, and pin‑compatible layout for easy PCB design. The datasheet provides absolute maximum ratings, thermal data, detailed electrical characteristics, and application hints for both DC‑ and AC‑coupling modes.
