MM1381, 1382, 1383 are three wideband RGB video amplifiers with OSD input, developed for use in monitors. The main differences between them are video amp bandwidth, output rise time, and output fall time.
The MM1381, MM1382 and MM1383 are monolithic IC video amplifiers designed for high‑resolution RGB monitors with on‑screen‑display (OSD) capability. Each device provides a wideband video amp, TTL‑level OSD inputs, and built‑in contrast and drive controls.
Key specifications include video‑amp bandwidth ranging from 85 MHz to 140 MHz, fast output rise/fall times (2.3 ns‑4.5 ns), and a 12 V operating supply. The datasheet lists pin functions, absolute maximum ratings, and recommended external components for optimal performance.
