This parameter is measured with the recommended copper heat sink pattern on a 1-layer PCB, 4 in2 5-in
× 5-in PCB,
1 oz. copper, 2-in
× 2-in coverage.
This parameter is measured with the recommended copper heat sink pattern on an 8-layer PCB, 6.9 in2 1.5-in
× 2-in PCB,
1 oz. copper with layers 1, 2, 4, 5, 7, and 8 at 5% coverage (0.9 in2) and layers 3 and 6 at 100% coverage (6 in2).
The maximum ambient temperature depends on the heatsinking ability of the PCB system. Using the 0 CFM
and 300 CFM data from the dissipation rating table, the derating factor for the PWP package with 6.9 in2 of
copper area on a multilayer PCB is 22 mW/
°C and 54 mW/°C respectively. Converting this to ΘJA:

To calculate maximum ambient temperatures, first consider that the numbers from the dissipation graphs are
per channel so the dissipated heat needs to be doubled for two channel operation. Given
ΘJA, the maximum
allowable junction temperature, and the total internal dissipation, the maximum ambient temperature can be
calculated with the following equation. The maximum recommended junction temperature for the TPA0102 is
150
°C. The internal dissipation figures are taken from the Power Dissipation vs Output Power graphs.

+ 114°C (15 dB headroom, 0 CFM)
NOTE:
Internal dissipation of 0.4 W is estimated for a 1.5-W system with 15 dB headroom per channel.
Table 4 shows that for most applications no airflow is required to keep junction temperatures in the specified
range. The TPA0102 is designed with thermal protection that turns the device off when the junction temperature
surpasses 150
°C to prevent damage to the IC. Table 4 was calculated for maximum listening volume without
distortion. When the output level is reduced the numbers in the table change significantly. Also, using 8-
speakers dramatically increases the thermal performance by increasing amplifier efficiency.
