ADD8704 is a 16V single-supply quad operational amplifier that is drop-in replacement for EL5420. It is suitable for TFT LCD monitor panels, TFT LCD notebook panels, communications equipment, portable instrumentation and electronic games.
The ADD8704 is a single‑supply quad operational amplifier optimized for low‑cost TFT LCD notebook and monitor panels. Channels A and D swing to the rail for end‑point gamma references, while channels B and C provide high continuous and peak current drive for Vcom or repair amplifiers.
The device operates from 4.5 V to 16.5 V, delivers up to 35 mA continuous output current, and features a 6 V/µs slew rate, low offset voltage (15 mV), and excellent capacitive‑load drive capability. It is offered in 14‑lead TSSOP and 16‑lead LFCSP packages.
