1.4 W BTL audio amplifiers with digital
volume control and headphone sensing
TDA8552T; TDA8552TS
PINNING
Note
1.
For the SO20 (SOT163-1) package only: the ground
pins 1, 10, 11 and 20 are mechanically connected to
the leadframe and electrically to the substrate of the
die. On the PCB the ground pins can be connected to
a copper area to decrease the thermal resistance.
