Part Number: TAS5782M
Other Parts Discussed in Thread: TAS5756M, TAS5756MDCAEVM,

Hello

In same condition which is PVDD=12V 8ohm 1W, THD+N is different as following.

;TAS5782M 0.014%

;TAS5756M 0.007%

Is it due to difference of internal DAC performance ?

( Customer think so, but is it correct?

In regard to idle channel noise, both TAS5782M and TAS5756M is almost same...

Is data sheet correct?)

Hi Kanji,

Did you get these measurement data using TAS5782MEVM and TAS5756MDCAEVM separately? The analog performance of these two devices should be very close to each other.

Hello Andy-san

Thank you for your quick reply.

I had asked customer to evaluate THD using AP and Eval board.

As per customer, THD of TAS5782M and TAS5756M seems almost same and its fine.

Best Regards
