Part Number: TPA2017D2
Other Parts Discussed in Thread: TPA2018D1

Hello,

I have two questions about AGC. Could you help me?

Is my understanding about Figure 2. OUTPUT LEVEL VS INPUT LEVEL correct?
In Table 1, "(AGC1, AGC2) = (0, 1), AGC Limiter Function enabled" means "AGC is disable, but Limiter is enable", correct?
Regarding Table 2, the default value can be changed by factory settings. How much is the adjustable range?

Regards,
Kazuto

Hi Kazuto,

You're correct on the mode descriptions.
Regarding table 2, modifying default values requires very specific business, this may be hard to get at this time.

Hi Ivan, if the following sentence is correct, does it means the datasheet contains an error? If so, will it be corrected?

Secondly, how much is the adjustable range of AGC at factory setting? If it's difficult to put the answer here, please send me an offline message.

Kazuto

Hi Kazuto,

Regarding data sheet statement, I agree that one is confusing perhaps it's a typo.

The adjustable range is similar to TPA2018D1, however as I mentioned the requirements to request this kind of change in the process in considerable, I may need to loop you in a discussion with marketing team. Please let me know.
