The SGM4810 is a dual audio power amplifier with active high shutdown mode. It is designed to maximize audio performance in portable applications. The audio power amplifier is designed for the portable application that needs low-component count and can operate from a single 2.5V to 5.5V power supply. Under the condition of using a 5.0V power supply to drive a 16Ω speaker, it can deliver a continuous average power of 158mW per channel, and the distortion (THD+N) is typically 0.1%.
The SGM4810 provides an active-high micro-power consumption shutdown mode which is controlled externally and an internal thermal shutdown protection.
SGM4810 is applied to low power portable systems. Bootstrap capacitors or snubber networks are not needed.
The SGM4810 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor) for maximum flexibility.
The SGM4810 is available in a Green MSOP-8 package. It operates over an ambient temperature range of -40℃ to +85℃.
