Hi all,
My customer want to use TAS5754/6 in 30W stereo, 0.05% THD+N condition and they have EVM already. They have questions now:
1. They test TAS5754 EVM in 19V and 24V. 5754 can meet 30W 0.1% THD+N at these power supplied but the performance is very margin. Is there any design guide for customer to improve THD+N in 19V or 24V power supply? By datasheet's description, 5754 can have 40W/ch in VPVDD = 24 V, SPK_GAIN = 26dBV, RSPK = 4 Ω, THD+N = 0.1% but 5756 has strange value in RSPK and VPDD...
2. Customer response that they there's no gain change when they modify the setting of spk_gain voltage. Is the setting modified by Hybridflow?
3. How long TAS575x can work in inst power condition?
Thanks for your kindly help.
