Design Notes
Ensure proper PCB layout with adequate ground planes and decoupling capacitors near the power pins. The thermal pad must be soldered to a copper area for heat dissipation. Use multiple vias to connect the thermal pad to the ground plane for improved thermal performance.
The TAS5827RHBR operates from 4.5V to 26.4V. Use a stable power supply with sufficient current capability. Place a 10uF ceramic capacitor close to each PVDD pin and a 0.1uF capacitor for high-frequency decoupling. Ensure the power supply can handle peak current demands during high-output conditions.
Do not exceed the maximum supply voltage of 26.4V. Ensure the digital input signal format (I2S/TDM) is correctly configured. In hardware control mode, set the switching frequency and gain via pins. Verify the I2C address and control settings to avoid misconfiguration.
Compliance Information
