The ADD8710 is a low cost, 10-channel gamma buffer with a VCOM driver that operates from a single supply. The part is designed for high resolution TFT LCD panels and is built on an advanced, high voltage CBCMOS process. The gamma buffers have a high slew rate, minimum 10 mA output current, and a high capacitive load drive capability. The VCOM buffer is capa...
The ADD8710 from Analog Devices is a low‑cost, 10‑channel gamma buffer with an integrated Vcom driver. It operates from a single supply (4.5 V‑18 V) and is designed for high‑resolution TFT LCD panels, providing continuous output currents of 10 mA per amplifier and peak Vcom currents of 250 mA.
The device features a compact 28‑lead TSSOP package, low offset voltage (12 mV typical), high slew rate (8 V/µs), and can drive large capacitive loads. It is specified for –40 °C to +85 °C operation and includes ESD protection.
