GENERAL DESCRIPTION
The LY8661 is a dual bridge-connected audio power
amplifier. It is capable of driving 4Ω speaker load at
a continuous average output of 2.0W / 10%
distortion (THD+N) from a 5.5V power supply. It
primarily designed for high quality application in
other portable communication device and portable
and desktop computers device.
The audio amplifier features low power consumption
in shutdown mode. Shutdown may be enabled by
either logic high or low depending on mode
selection(SOP package only). And it has an internal
thermal shutdown protection feature.
LY8661 audio amplifier was designed specifically to
provide high quality output power with a minimal
amount of external components. The LY8661 does
not require output capacitors, and it is ideally suited
for other low voltage applications or portable
electronic devices where minimal power
consumption is a primary requirement.
