SGM4895
1.3W Fully Differential
Audio Power Amplifier
GENERAL DESCRIPTION
The SGM4895 is a fully differential audio power
amplifier that is designed for portable communication
device applications and demanding applications in
mobile phones. It is capable of delivering 1.3W of
continuous average power into an 8Ω load with typically
1% distortion (THD+N) from a 5V battery voltage. It
operates from 2.5V to 5.5V power supply.
The SGM4895 features a low power consumption
shutdown mode. To facilitate this, shutdown may be
enabled by logic low. Additionally, the SGM4895
features an internal thermal shutdown protection
mechanism.
The SGM4895 contains advanced pop/click circuitry,
with a minimal amount of external components. All
these features make SGM4895 ideal for wireless
handsets and other low voltage applications where
minimal power consumption is a primary requirement.
The SGM4895 is available in Green TDFN-3×3-8L and
MSOP-8 (Exposed Pad) packages. It operates over an
ambient temperature range of -40℃ to +85℃.
