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

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.
