封装管脚图产品描述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 less than 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 °C to + 85 °C .产品特性Dual Channel, Differential Inputs132mW into 16Ω Load from 5V Power Supply at THD+N = 0.1% Typical (per Channel)82mW into 32Ω Load from 5V Power Supply at THD+N = 0.1% Typical (per Channel)2.7V to 5.5V OperationThermal Shutdown and Short Circuit ProtectionInternal Pop Reduction CircuitryInternal Mid-Rail GenerationLow Shutdown Current: 0.36μA (TYP) at 5VShutdown Pin is Compatible with 1.8V Logic-40 °C to + 85 °C Operating Temperature RangeAvailable in Green MSOP-10 Package
