TAS2560: Question of TAS2560 Pout vs Sample Rates

Part Number: TAS2560

Hi Sirs,

With the same test conditions of the VBAT ad load impedance. We got higher non-clipping output power with high sample rate. Is it a normal behavior?
48kHz: >5V non clipping voltage
16kHz: <5V non clipping voltage

How do we explain the measurement results?

BCLK=1.536MHz, 16bit LJ, 48kHz Sample Rate

 9dB -> w 98 04 09
10dB -> w 98 04 0a
15dB -> w 98 04 0f



BCLK=512kHz, 16bit LJ, 16kHz Sample Rate

 9dB -> w 98 04 09
10dB -> w 98 04 0a
15dB -> w 98 04 0f






Thank you and Best regards,
