Electrical Characteristics
(Notes 2, 11) (Continued)
Note 9:
In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be
derated. Maximum ambient temperature (T
A-MAX
) is dependent on the maximum operating junction temperature (T
= 125C), the maximum power
dissipation of the device in the application (P
D-MAX
), and the junction-to ambient thermal resistance of the part/package in the application (
θ
JA
), as given by the
following equation: T
A-MAX
= T
J-MAX-OP
(
θ
JA
D-MAX
).
Note 10:
Junction-to-ambient thermal resistance is highly application and board-layout dependent. In applications where high maximum power dissipation exists,
special care must be paid to thermal dissipation issues in board design.
Note 11:
Min and Max limits are guaranteed by design, test, or statistical analysis. Typical numbers are not guaranteed, but do represent the most likely norm.
Note 12:
Low-ESR Surface-Mount Ceramic Capacitors are used in setting electrical characteristics.
Note 13:
Audio block inactive.
Note 14:
In single-ended and in differential mode one audio buffer only is active and I
VDDA
will be reduced by 90 μA (typ).
Note 15:
V
REF
pin (Bandgap reference output) is for internal use only. A capacitor should always be placed between V
REF
and GND1.
