TDF8599
I2C-bus controlled dual channel class-D power amplier
13. Dynamic characteristics
[1]
Rs(L) is the sum of the inductor series resistance from the low-pass LC lter in the application together with all resistance from PCB
traces or wiring between the output pin of the TDF8599 and the inductor to the measurement point. LC lter dimensioning is L = 10
H,
C=1
F for 2 load and L = 5 H, C = 2.2 F for 4 load.
[2]
Output power is measured indirectly based on RDSon measurement.
[3]
Total harmonic distortion is measured at the bandwidth of 22 Hz to 20 kHz, AES brick wall. The maximum limit is guaranteed but may
not be 100 % tested.
[4]
Vripple =Vripple(max) = 2 V p-p; Rs =0 .
