Part Number: TPA3140D2 Other Parts Discussed in Thread: OPA994 hi i Need Part no & circuit design support for below application.
We need an Amplitude modulation circuit/IC, we will provide two inputs to that AM IC one is Carrier wave with 4kHz and 10Vp…
Part Number: TPA3140D2 Hello, I have a question regarding audio output.
AVCC: 14.7v and current test tone audio signal 1KHZ 600mVpp are applied.
The circuit is identical to the EVM circuit.
There are three problems:
1. /SD: 0.2V 2. OUTPL: 1.4V 3. OUTNL…
Part Number: TPA3140D2 Hello. I uses a TPA3140D2 Audio AMP and 4 ohm Speaker.
I input a Test tone (1KHz, 0dBm) and Output Sound is available.
There is a problem measuring the output audio signal waveform using an oscilloscope.
For example, I applied a…
Part Number: TPA3140D2 Hello.
I have a question about TPA3140D2 Gain Setting. The current SLOU405 TPA3140D2EVM User's Guide 3.1 TPA3140D2 EVM Schematic is referred to to design the same circuit.
A 4ohm, 10W speaker is connected to the OUTPL/OUTPN…
Part Number: TPA3140D2 Hi Team,
Do we have any documentation or app notes that shows how to compute the power dissipation of a Class D amp like our TPA3140D2?
Thanks!

Hi Brian,
You should short 22uH inductor between two ground, and then check issue can be fixed on some good boards. That means the issue will not happen again. It is meaningless to check on failure device because the device was damaged and can not recover…
Part Number: TPA3140D2 Other Parts Discussed in Thread: TPA3144D2
(Amendment: Please ignore my questions below as after testing, and confirmed from another thread, over-voltage-locked-out will turn-off the IC above 15+ Volt. So, how can I delete this…
Part Number: TPA3140D2PWPEVM Other Parts Discussed in Thread: TPA3144D2 , TPA3140D2 Hello Team,
I see that the TPA3144D2 IC does not have a EVM, is it possible to use the tpa3140d2pwpevm but switch out the IC for the TPA3144D2. Looking at the datasheet both…
Part Number: TPA3140D2 Dear Sirs,
My customer asked us about additional capacitor between SD&FAULT pins to GND for TPA3140D2.
SD and FAULT pins are shorted.
Additional capacitor rating is 0.1uF.
Is it OK to add this capacitor?
Although I think that…
Part Number: TPA3140D2 Dear Sirs,
My customer asked us about shutdown with changing supply voltage (max) for TPA3140D2.
So I confirmed the phenomenon with EVM.
When raising PVDD to 15.8 V, the output stopped. There is no change in the FAULT terminal voltage…
