FEATURES
GENERAL DESCRIPTION
2.5V~5.5V Power supply.
The LY8895 is a 1.4 Watt audio power amplifier. And
the LY8895 primarily designed for high quality
application in other portable communication device.
It is capable of driving 8Ω speaker load at a
continuous average output of 1.4W / 10% distortion
(THD+N) from a 5.0V power supply.
A feature of the LY8895 amplifier to switch BTL
mode and headphone mode (single-ended) is
accomplished using the headphone sense pin. And
the LY8895 audio amplifier features low power
consumption shutdown mode. It is achieved by
driving the shutdown pin with logic low. Besides the
LY8895 has an internal thermal shutdown protection
feature.
