Hi Sirs,

Would you pls assist us to generate official TAS5704 THD+N vs Pout curve all the way to 25W Pout with 6.8ohm load, 24.6V PVCC, -1.68dBFS I2S input?

Than you and Best regards,

    Hi, Wayne,

    First of all, I would like to mention that this device is quite old, and right now we have newer devices with much better performance, lower cost, reduced BOM and easier end-system integration, so I would recommend to take a look to try moving to our closed loop TAS5760M or TAS5756M/54M devices. 

    Generating this plot might be complicated as I don't have an EVM right now or a 6.8 Ohm load.

    Hello Diego Meléndez,

    since the EVM of TAS5704 is EOL and BU can;t provide any EVM for us to debug custoemr issue. Do we have other alternative P2P solution with TAS5704 ?

    If yes, we can re-work TAS5704 then test the Pout curve in field side. Pelase kidnly suggest how to process on it, thanks.

    Hi, Ray,

    Unfortunately, there is no solution amplifier p2p compatible with the TAS5704. As mentioned before, this device is quite old, so It is complicated to get the tools to evaluate the part.
