GENERAL DESCRIPTION
The ADD8704 is a single-supply quad operational amplifier that
has been optimized for today’s low cost TFT LCD notebook and
monitor panels. Output channels A and D swing to the rail for
use as end-point gamma references. Output channels B and C
provide high continuous and peak current drive for use as VCOM
or repair amplifiers; they can also be used as midpoint gamma
references. All four amplifiers have excellent transient response
and have high slew rate and capacitive load drive capability. The
ADD8704 is specified over the –40°C to +85°C temperature
range and is available in either a 14-lead TSSOP or a 16-lead
LFCSP package for thin, portable applications.
