ADD8710:  10-Channel Gamma Buffer with VCOM Driver

Product Description

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 capable of delivering 250 mA of peak current and can also drive large capacitive loads. The ADD8710 offers a wide supply range and offset voltages below 12 mV.

The ADD8710 is specified over the −40°C to +85°C tempera-ture range and is available in a Pb-free, 28-lead TSSOP package.
