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.
