TAS5825P: 1SPW THD

switch

Part Number: TAS5825P

Tool/software:

Hi ti team，

The customer is using 1SPW Modulation and found that the THD is too large. The datasheet only has THD curves for Hybrid Modulation and BD. Please provide THD curves for 1SPW Modulation.

PVDD=16.4V   Load = 4 Ω    Output Powe=25W

    Hi Switch,

    The plot you included is a sweep across power and not a fixed power level as mentioned in your question. What plot or data point is it exactly that's needed?

    1SPW gives the customer lower idle current at the cost of slightly worse THD as mentioned in the datasheet. Hybrid modulation allows for the low Idle current while not compromising on the THD. I would recommend customer switch to this modulation scheme.

    Regards,

    Ramsey
