The device accepts digital I2S audio input and provides I2C control for configuring the on-chip DSP functions including parametric EQ, dynamic range compression (DRC), and biquad filters. With up to 92% efficiency, the amplifier typically requires no external heatsink. The VQFN-28 package provides a compact footprint for space-constrained audio applications such as TV soundbars, portable speakers, and smart speakers.","working_principle":"The TAS5722LRSMR receives digital audio data through the I2S interface and processes it through the integrated DSP engine. The DSP applies configurable audio processing including biquad filters for equalization, dynamic range compression for loudness management, and mixing functions. The processed digital audio is then converted to a PWM signal that drives the output H-bridge power stage. The Class-D output stage uses high-frequency switching to modulate the supply voltage, and an external LC filter reconstructs the analog audio signal. The integrated feedback loop ensures low distortion and good power supply rejection. Comprehensive protection circuits monitor output current, die temperature, and supply voltage, automatically shutting down the output stage if any parameter exceeds safe limits.","pin_description":"
