SGM4996
1.3 Watt 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 to an 8Ω load with 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, a minimal count of external components and low-power shutdown mode. All the features make SGM4996 ideal for wireless handts and other low voltage applications where minimal power consumption is a primary requirement.
The SGM4996 is available in Green MSOP10, DFN3×3-10L and MSOP8 packages. It operates over an ambient temperature range of -40℃ to +85℃.

Note: Stress above tho listed under Absolute Maximum Ratings may cau permanent damage to the device. This is a stress rating only; functional operation of the device at the or any other conditions above tho indicated in the operational ction of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to obrve proper handling and installation procedures can cau damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be more susceptible to damage becau very small parametric changes could cau the device not to meet its published specifications.
