The ADD8704 is a single‑supply quad operational amplifier optimized for low‑cost TFT LCD notebook and monitor panels. It offers four independent channels: A and D swing to the rail for end‑point gamma references, while B and C provide high continuous (35 mA) and peak (200 mA) current drive for Vcom or repair amplifiers. The device operates from 4.5 V to 16.5 V, is unity‑gain stable with large capacitive loads, and is available in 14‑lead TSSOP (RU) and 16‑lead LFCSP (CP) packages.
Typical applications include TFT LCD monitor and notebook panels, communications equipment, portable instrumentation, and electronic games. Key electrical characteristics include a 6 V/µs slew rate, 15 mV typical offset voltage, 700 µA supply current per amplifier, and a gain‑bandwidth product of 58 MHz.
