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.

ABSOLUTE MAXIMUM RATINGS
Table 3. ADD8704 Stress Ratings1
Table 4. Package Characteristics
1 Stresses above those listed under Absolute Maximum Ratings may cause
permanent damage to the device. This is a stress rating only; functional
operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
2 θJA is specified for worst-case conditions, i.e., θJA is specified for devices
soldered onto a circuit board for surface-mount packages.
3 DAP is soldered down to PCB.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this part features proprietary
ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic
discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of
functionality.
