TAS5825M: Optimal PWM switching frequency and loop bandwidth

Part Number: TAS5825M

hi,

how does the pwm switching frequency and loop bandwidth affect power consumption and audio quality?

i can't seem to find that information in the datasheet.

thanks, jacob

  • Hello Jacob,

    Typically most significant difference can be seen between different modulation schemes but typically lower switching frequency offers better efficiency and higher loop bandwidth offers better performance. Please note Table 7-3. Loop Bandwidth and Switching Frequency Setting in the datasheet though for guidance on appropriate loop bandwidth settings for each configuration.

    Best regards,

    Luis
