The SGM4812C is a stereo 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 2.7V 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 132mW per channel, and the distortion (THD+N) is typically 0.1%.

No external compensation is required for the amplifier gain, which is externally configured through two resistors for each input channel.

The SGM4812C provides an active-high, micro-power consumption shutdown mode which is controlled externally and an internal thermal shutdown protection.

The SGM4812C is available in Green MSOP-10 package. It operates over an ambient temperature range of -40 to +85.
