TPA0211: Sound emission from the shutdown return

Taku Murayama

Part Number: TPA0211
Other Parts Discussed in Thread: TPA6211A1,

Tool/software:

①
Is there a regulation until the sound is emitted from the shutdown return?
I am very sorry that I could not find it from the specification sheet.

Under certain conditions (bypass pin capacitance).

②
On your website, "TPA6211A1" seems to be upward compatible with "TPA0211", but are there any concerns about "TPA0211" -> "TPA6211A1"?

Also, please refer to other recommended parts if available.

③
For the parts introduced in this article, are there any regulations until the shutdown is restored and the sound is emitted? ②
(TPA6211A1 is stated as 25ms at 0.1 uF)

Hi Murayama,

There's a previous similar question available for reference: TPA0211 - The customer would like to know the "enable to audio output active" time delay specification - Audio - INTERNAL forum - Audio - INTERNAL - TI E2E support forums

TPA6211A1 is a more recently developed device, and it's a fully differential amplifier as compared to TPA0211 being single-ended only. TPA6211A1 would be able to deliver higher output power.

I would like to compare it with the TPA6211A1 0.1uF 25ms, so could you tell me the time of TPA0211 under the same conditions?

Hi Murayama,

There's EVM available online, the test can be run with it: TPA0211EVM Evaluation board | TI.com

If you need me to test, please allow until end of next week, I have to order an EVM myself and allocate time for rework and testing. Please let me know if the test on our side is required.

Hi Murayama,

Ivan is out of the office for the first half of this week. I have ordered the TPA0211EVM, it may be early next week before it is received, and we can do this testing on our side.

Regards,
Arthur

Hi Maruyama,

The test with 0.1uF results in about 140ms:
