SGM4812
132mW Differential Input,
Stereo Audio Power Amplifier
GENERAL DESCRIPTION
The SGM4812 is a stereo audio power amplifier with
differential inputs. Operating on a single 5V power
supply, it delivers 132mW of continuous RMS power
per channel into a 16Ω loads with typically 0.1%
THD+N. Amplifier gain is externally configured by
means of two resistors per input channel and does not
require external compensation.
The SGM4812 is designed to maximize audio
performance in portable communication device
applications such as mobile phone. The portable
application requires audio power amplifier has
minimum of external components and can operate from
a single 2.7V to 5.5V power supply.
The SGM4812 features an externally controlled,
active-high, micro-power consumption shutdown mode.
Additionally, the SGM4812 features an internal thermal
shutdown and short circuit protection mechanism.
The SGM4812 is available in Green MSOP-10 package.
It operates over an ambient temperature range of -40℃
to +85℃.
