General Description

BD28412MUV is 9 W + 9 W stereo (or 18 W monaural under parallel connection) class D amplifier which can output power without an external heat sink.

This LSI has built-in precise oscillator which generate selectable switching frequencies, so AM radio interference can be avoided.

In addition, 2.1 Ch audio system can be achieved by master and slave operation without caring about beat noise.

Key Features

  • Analog Differential Input.
  • Low Standby Current.
  • Output Feedback Circuitry Prevents Sound Quality Degradation Caused by Power Supply Voltage Fluctuation, Achieves Low Noise and Low Distortion, Eliminates the Need of Large Electrolytic-Capacitors for Decoupling.
  • Power Limit Function (Linearly-programmable for voltage of PLIMIT).
  • Selectable Switching Frequency (AM Avoidance Function).
  • Synchronization Control is Supported (Selectable Master and Slave Operation).
  • P.
