The SGM4871 is a mono bridged audio power amplifier
that is designed for portable communication device
applications and demanding applications in mobile
phones. SGM4871YPS8 is capable of delivering 2.4W of
continuous average power into a 4Ω load with typically
10% distortion (THD+N) from a 5V battery voltage. It
operates from 2.5V to 5.5V power supply.
The SGM4871’s micro-power shutdown mode (ISD =
0.07μA TYP) is activated when V+ is applied to the SHDN
pin. Since the SGM4871 does not require output coupling
capacitors, bootstrap capacitors, or snubber networks, it
is ideally suited for low power portable systems that
require minimum volume and weight.
The SGM4871 is unity-gain stable and can be configured
by external gain-setting resistors. Additionally, the
SGM4871 features an internal thermal shutdown
protection mechanism. SGM4871YPS8/TR SGM4871YS8/TR资料下载
