Characterization curves

TDA7492MV

The following characterization curves were made using the TDA7492MV exposed-pad-down

test board with VCC = 25 V, a signal frequency of 1 kHz and an output power of 1 W unless

otherwise specified.

The LC filter for the 8-Ω load uses components of 33 µH and 220 nF and for the 6-Ω load

22 µH and 220 nF.
