Texas Instruments TAS5830 65W Stereo Class-D Amplifier

Texas Instruments TAS5830 65W Stereo Class-D Amplifier is a stereo high-performance, closed-loop Class-D amplifier with an integrated audio processor and up to 192kHz audio support. When setting the device into Hardware control mode, TAS5830 supports selecting switching frequency, analog gain, BTL/PBTL mode, and cycle-by-cycle current limit threshold through pin configuration. This mode is designed to eliminate end system software driver integration efforts.

The Texas Instruments TAS5830 also provides DSP features, rattle suppression, and a frequency limiter. Rattle suppression reduces the gain of the signal at frequencies that cause rattle through interaction with the speaker enclosure, improving sound quality. The frequency limiter process senses the input level, dynamically limits EQ's gain, and helps SPL without phase change.
