ENVIRONMENTAL CONDITIONS
Thermal Characteristics
The ADSP-21060KS and ADSP-21060LKS are packaged in a
240-lead thermally enhanced MQFP. The top surface of the
package contains a copper slug from which most of the die heat
is dissipated. The slug is flush with the top surface of the pack-
age. Note that the copper slug is internally connected to GND
through the device substrate. The ADSP-21060KB and ADSP-
21060LKB are plastic ball grid arrays. The
θ
JC
for the PBGA
package is 1.7
°
C/Q.
The ADSP-2106x is specified for a case temperature (T
CASE
).
To ensure that the T
CASE
data sheet specification is not ex-
ceeded, a heatsink and/or an air flow source may be used. A
heatsink should be attached with a thermal adhesive.
