ADD8702 is a 12-channel gamma buffer with VCOM buffer. It can generate programmable gamma reference voltages on 12 channels and perform mask programming. In addition, it has an adjustable VCOM buffer that can output high and low voltages on VCOM. The product's output current is 10mA, and the VCOM peak output current is 250mA. In addition, the product's output pins are compatible and can be used for fast load changes.
The Analog Devices ADD8702 is a low cost, mask programmable, 12-channel gamma reference generator plus an adjustable V COM driver designed to provide gamma correction for high resolution TFT LCD panels. The device features a complete programmed set of gamma voltage references that settle quickly to load change.
