AN12974A Stereo Power Amplifier With Built-in AGC Circuitry And SPATIALIZER
The AN12979A is designed for communication applications, providing a robust solution for audio amplification. Its stereo BTL (Bridge-Tied Load) configuration allows for efficient power delivery to speakers, enhancing audio performance while minimizing distortion. The built-in Automatic Gain Control (AGC) circuit is a critical feature that ensures consistent output levels, preventing audio clipping that can occur during high-volume playback. This is particularly important in communication systems, where clarity and fidelity are paramount.
The capability to control the amplifier's operation through the I2C bus is a significant advantage. This digital control interface allows for seamless integration into more extensive systems, enabling features such as remote operation and automated adjustments based on the system's requirements. The standby function can be engaged or disengaged through this interface, which helps in power management, ensuring that the amplifier consumes energy only when required.
Overall, the AN12979A amplifier is a versatile component suitable for various audio applications, delivering high-quality sound while incorporating advanced features for user control and protection.ASSP For Communication AN12979A AN12979A is the stereo BTL Amplifier which contained the AGC circuit for clip prevention of a speaker output. 2 This IC performs a mode change by the I C bus control system.
