TAS6424M-Q1: Question for AC diag and mute

Kazuki Kuramochi

Part Number: TAS6424M-Q1

Hello expert,

I have 3questions for AC diag.
First, datasheet said AC diag time is 520m[s].
Is this mean this AC diag time is measured from datasheet 9.3.7.3.1's step1?

Second, Could I change Mute pin status during AC diag? For example, I change Mute pin from High to Low.
Also, I think I can use AC diag regardless of mute pin status as long as it is not change during AC diag. Is this right?

Thank you and best regards,

Kuramochi-san,

AC diag time is measured from datasheet 9.3.7.3.1's Impedance Magnitude Measurement section.

I need to confirm whether MUTE pin will impact the AC diagnostic, i will come back to you late tomorrow.

Hi Dylan-san,

Do you mean it is measured from step1 of setting channel to Hiz?
Anyway, I'm waiting for your answer regarding mute pin.

Best regards,

Kuramochi-san,

Please give me one more day to get this. i didn't have time to check it in lab. I will feedback you on Monday.

Luramochi-san,

MUTE pin does not impact AC diagnostic. so whatever the status it is, not related to AC diagnsotic measurement.

About the time, i mean AC diag time is measured from datasheet 9.3.7.3.1's Impedance Magnitude Measurement section step 1 to step 5
