GENERAL DESCRIPTION

The ADD8706 is a single-supply, 5-channel buffer with a separate VCOM amplifier that has been optimized for today’s low cost TFT LCD notebook and monitor panels. The top and bottom channels swing to the top/bottom rails, respectively, and can be used as end-point gamma references. The middle channels are ideal for midpoint gamma references. The VCOM amplifier provides very high continuous and peak currents. All channels have excellent transient response as well as high slew rate and capacitive load drive capability. The ADD8706 is specified over the –40°C to +85°C temperature range. The ADD8706 is available in a 16-lead TSSOP package.
