TS34119
Low Power Audio Amplifier
6/13
Version: A07
Design Guideline
POWER DISSIPATION
Figure 8 to 10 indicate the device dissipation (within the IC) for various combinations of VCC, RL, and load power.
The maximum power which can safely be dissipated within the TS34119 is found from the following equation:
PD= (140oC - Ta) / ja
Where Ta is the ambient temperature; and ja is the package thermal resistance (100
oC/W for the standard DIP
package, and 180
oC/W for the surface mount package.) The power dissipated within the TS34119, in a given
application, it is found from the following equation: PD= (VCC × ICC) + (IRMS × VCC) - (RL × IRMS2)
Where ICC is obtained from Figure 15; and IRMS is the RMS current at the load; and RL is load resistance. Figure 8
to 10, along with Figure 11 to 13 (distortion curves), and a peak working load current of ±200mA, define the operating
range for the TS34119. The operating range is further defined in terms of allowable load power in Figure 14 for loads
of 8Ω, 16Ω and 32Ω. The left (ascending) portion of each of the three curves is defined by the power level at which
10% distortion occurs. The center flat portion of each curve is defined by the maximum output current capability of the
TS34119. The right (descending) portion of each curve is defined by the maximum internal power dissipation of the IC
at 25
oC. At higher ambient temperatures, the maximum load power must be reduced according to the above
equations. Operating the device beyond the current and junction temperature limits will degrade long-term reliability.
