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.
