TPA701
700-mW MONO LOW-VOLTAGE AUDIO POWER AMPLIFIER

DALLAS, TEXAS 75265
APPLICATION INFORMATION
headroom and thermal considerations (continued)
This is valuable information to consider when attempting to estimate the heat dissipation requirements for the
amplifier system. Comparing the absolute worst case, which is 700 mW of continuous power output with 0 dB
of headroom, against 12 dB and 15 dB applications drastically affects maximum ambient temperature ratings
for the system. Using the power dissipation curves for a 5-V, 8-
system, the internal dissipation in the TPA701
and maximum ambient temperatures is shown in Table 2.
