Part Number: TPA3132D2

Hi all,

I have a question on TPA3132D2.
Is Output Power=30W output possible when used in MONO mode (Datasheet p.20 7.4.1)?

The customer plans to operate the TPA3132D2 with the following specifications.

・PVCC = 12V
・RL = 8Ω
・Output Power = 30W
・MONO mode

Is it possible to use TPA3132D2 with this specification?
I think it can be used in the 6.6 AC Electrical Characteristics description.

Hi Ishiwata,

From customer application description, TPA3132 has the capacity to dirve 30W at 8ohm load, PVCC=12V using MONO mode.

Hi Derek,

I'm sorry. There are additional confirmations.
What is the maximum output power in customer specifications (PVCC=12V, RL=8Ω, MONOmode)?
Or can it be calculated?

Hi Ishiwata,

I am sorry that I calculated power used error load impedance before.

PVCC=12V, RL=8Ω, MONO mode can not drive to 30W at 10% THD. The drive capacity is 20W at 10% THD.

You can see the figure 15, the BTL data at 8ohm load. Mono mode data should be twice times as BTL mode.

I am sorry for the inconvenience.

Regards,

Derek

Hi Derek,

I wasn't looking at the datasheet either.
I understand. It is at PVCC=12V in the graph below.

Are there any amplifiers that can meet customer specifications?
I want you to tell me about that product.

Best Regards,
Ishiwata

Hi Ishiwata,

It seems no device can support customer application.

Can they change load to 4ohm or adjust PVDD to high voltage?

Hi Derek,

My apologies for a late reply here.

Advised the customer to change load and PVDD.
Thank you for your support.
