SGM4996
1.3W Fully Differential Audio Power
Amplifier with Selectable Shutdown
GENERAL DESCRIPTION
The SGM4996 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 SGM4996 features a low power consumption
shutdown mode. To be flexible, shutdown may be
enabled by either a logic high or low depending on the
voltage applied on the SD MODE pin. Additionally, the
SGM4996 features an internal thermal shutdown
protection mechanism.
The SGM4996 contains advanced pop/click circuitry, with
a minimal amount of external components. All these
features make SGM4996 ideal for wireless handsets and
other low voltage applications where minimal power
consumption is a primary requirement.
The SGM4996 is available in Green MSOP-10,
TDFN-3×3-10L and MSOP-8 packages. It operates over
an ambient temperature range of -40℃ to +85℃.
