Fig.9 Single-chip class-D audio amplifier application diagram.
(1) BTL: remove IN2, R8, R9, C18, C19, C21 and close J3 and J4.
(2) BTL: connect loudspeaker between OUT1+ and OUT2
.
(3) BTL: R1 and R2 are only required when an asymmetrical supply is used (V
SS
= 0 V).
(4) In case of hum close J1 and J2.
Every decoupling to ground (plane) must be made as close as possible to the pin.
To handle 20 Hz under all conditions in stereo SE mode, the external power supply
needs to have a capacitance of at least 4700
μ
