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"?…
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.
Regards,

Part Number: TAD5142 Other Parts Discussed in Thread: TPA6139A2 Tool/software: Hi All,
I have some questions for TAD5142.
(1) I used it as a headphone amplifier, but does it have OCP on the output?
(2) In answer in (1), if an OCP is installed, will the…
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 power…
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 Other Parts Discussed in Thread: PCM5101A In the TPA6139A2 datasheet section10.2.2.1.4, it says
"DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the TPA6139A2."…
Part Number: TPA6139A2 Other Parts Discussed in Thread: TPA6132A2 , I have been happy with electrical performance of the TPA6132A2, but it is the only QFN in my design and QFN soldering problems have been my most common cause of board failures. I wanted…
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). Thank…
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.
TPA6138A2 / TPA6139A2 don't support 8ohms load
I shorted the inputs of LM4880 to GND before the input AC coupling caps and still pops
Also tried to connect the LM4880 directly to the DAC, bypassing the buffer (NE5532), still pops.
Any suggestions…
