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!

Part Number: TPA3140D2 Hello,
We are seeing significant failure rates with this audio amp. We can replace a bad one with another device with success, and install the bad one onto a good board and the issue follows.
No audio coming out of the device. Device…
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…
