AD8113
–5–
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 the AD8113 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.
WARNING!
ESD SENSITIVE DEVICE
POWER DISSIPATION
The AD8113 is operated with ±5 V to ± 12 V supplies and
can drive loads down to 150 Ω (± 5 V) or 600 Ω (±12 V),
resulting in a large range of possible power dissipations. For
this reason, extra care must be taken derating the operating
conditions based on ambient temperature.
Packaged in a 100-lead LQFP, the AD8113 junction-to-ambient
thermal impedance (θ
JA
) is 40°C/W. For long-term reliability,
the maximum allowed junction temperature of the plastic-
encapsulated die should not exceed 150°C. Temporarily exceeding
this limit may cause a shift in parametric performance due to a
change in the stresses exerted on the die by the package. Exceeding
a junction temperature of 175°C for an extended period can result
in device failure. The following curve shows the range of allowed
power dissipations that meet these conditions over the commercial
range of ambient temperatures.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent 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
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

To avoid differential input breakdown, in no case should one-half the output
voltage (1/2 V

) and any input voltage be greater than 10 V potential differen-
tial. See output voltage swing specification for linear output range.
