THS4302
SLOS403G–OCTOBER 2002–REVISED JANUARY 2005
The thermal characteristics of the device are dictated
by the package and the PC board. For a given
Θ
JA
,
maximum power dissipation for a package can be
calculated using the following formula.
When determining whether or not the device satisfies
the maximum power dissipation requirement, it is
important to consider not only quiescent power dissi-
pation, but also dynamic power dissipation. Often
maximum power is difficult to quantify because the
signal pattern is inconsistent, but an estimate of the
RMS power dissipation can provide visibility into a
possible problem.
Texas Instruments is committed to providing its cus-
tomers with the highest quality of applications sup-
port. To support this goal, an evaluation board has
been developed for the THS4302 operational ampli-
fier. The evaluation board is available and easy to
use allowing for straight-forward evaluation of the
device. This evaluation board can be obtained by
ordering through the Texas Instruments Web site,
www.ti.com, or through your local Texas Instruments
Sales Representative. A schematic for the evaluation
board with default component values is shown in
vide insight into design flexibility
