General Description
The PAM8615 is a 16W
/
32W
(
per channel
)
efficient
,
Class
-
D audio power amplifier for
driving stereo speakers in a single
-
ended
configuration or mono bridge
-
tied speaker
.
The
PAM8615 can drive single
-
ended speakers as
low as 4
Ω .
Due to the low power dissipation
and high efficiency the device can be used
without any external heat sink when playing
music
.
Stereo speaker volume is controlled with a dc
voltage applied to the volume control terminal
offering a range of gain from
-
40 dB to 36 dB
.
