BD28412MUV - 9W+9W Analog Input Class D Speaker Amplifier

Datasheet Summary

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.

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.

Datasheet Low Power Consumption Class D Speaker Amplifier series 9 W + 9 W Analog Input Class D Stereo Speaker Amplifier BD28412MUV 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. This LSI achieves lower power consumption under low output power, and suitable for speaker systems in which battery is equipped such as wireless speakers.
