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
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Maximum Power Dissipation
The maximum safe power dissipation for the ADA4851-1/
ADA4851-2/ADA4851-4 is limited by the associated rise in
junction temperature (T
J
) on the die. At approximately 150
°
C,
which is the glass transition temperature, the plastic changes its
properties. Even temporarily exceeding this temperature limit
may change the stresses that the package exerts on the die,
permanently shifting the parametric performance of the
amplifiers. Exceeding a junction temperature of 150°C for an
extended period can result in changes in silicon devices,
potentially causing degradation or loss of functionality.

The power dissipated in the package (P
D
) is the sum of the
quiescent power dissipation and the power dissipated in the die
due to the amplifiers’ drive at the output. The quiescent power
is the voltage between the supply pins (V
S
) times the quiescent
current (I
S
).

Airflow increases heat dissipation, effectively reducing θ
JA
.
Also, more metal directly in contact with the package leads and
through holes under the device reduces θ
JA
.

package vs. the ambient temperature for the 6-lead SOT-23
(170°C/W), the 8-lead MSOP (150°C/W), and the 14-lead
TSSOP (120°C/W) on a JEDEC standard 4-layer board. θ

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 product 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.
