Part Number: TPA6139A2 Hello,
I have a question about Power on Sequence. of "TPA6139A2PWR".
In my circuit, 3.3V is applied to "MUTE" pin, while VDD is "Low".
Is the MUTE pin tolerance? Is this harmful to "TPA6139A2PWR"?
Best regards,
Part Number: TPA6139A2 Hello,
It is simple question, what is internal negative voltage -Vss?
We want to know it to expect maximum output signal voltage swing, but there is no specification of -Vss on the datasheet.

Part Number: TPA6139A2 Dear Support,
I am using the TPA6139A2 for an audio application. I am not sure what should be the optimal input voltage range for the audio signal in order to avoid distortion.
Thank you in advance
Part Number: TPA6139A2 Hi Team,
My customer is designing TPS6139A2 in his schematic and would like to know the thermal performance when the worst case happen.
The supply voltage is 3.3V, in the worst case the max. limited output current is 60mA. The…

Eduardo,
It is safe to connect NC pins to GND. There is no internal connection to these pins.

Part Number: TPA6139A2 Dear team,
Customers want to know if TPA6139A2 can work on ubuntu 18.04 / Debian 9 platform??
Would you please help to confirm it??
Thank you very much.
Part Number: TPA6139A2 Hi Team, Our customer is asking if the output signal is in phase with the input signal in TPA6139A2? He wants to know if a positive going voltage on the input provides a positive going voltage on the output (or if its inverted)…
Hi,
Installed the 1uF cap between pin 5 (Vss) and GND using a completely new device, also replaced the 5V to 3V3 LDO; different behavior, but no success.
- The LDO was again totally destroyed.
- Nothing out of the TPA6139A2.
Surely there is…
