Part Number: TPA3112D1 I have made a PCB with the sample circuit in the data sheet. I am using 9, 10, 11 or 12V for the power supply voltage. I am using 1uF film caps t block DC at the inputs. I am using 20dB gain so it has about a 60K input impedance…
Part Number: TPA3112D1 I know TPA3112D1 has gain control, but when I adjusted to 26db, the sound output was trashed with noise, and the audio is basically unusable. (with EVM's setup).
Now, for other parts of the circuit, it also has a dedicated audio…
Part Number: TPA3112D1 Hi team,
my customer use TPA3112D1, when they do the simulation, they found that there were simulation results and specifications that were not correct:
The simulation results are Vbias=0V, and DS and DEMO actually measure 3V ,…
Part Number: TPA3112D1 I've assembled my board and was having trouble identifying why the fault pin would stay low (unless I put the IC in shutdown, obviously). Finally, after removing the ferrite beads on the output, I am able to bring the device out…
Part Number: TPA3112D1 Hi Team,
We would like to ask your help regarding the issue with our customer's board which has TPA3112D1PWPR . According to our customer,
We use your TPA3112D1PWPR in several of our products.
With our most recent design we have…
Part Number: TPA3112D1
At present, TPA311D1 is used to design the following circuit diagram, but no matter how the input waveform changes, the output will not change, can you help to check which side is designed, is there…
Part Number: TPA3112D1 I am having intermittent power-up issues. The fault pin stays low. I'm using three devices in similar circuits, all connected to the same power supply. Sometimes one or two devices go into fault mode. Sometimes all three work…
Part Number: TPA3112D1 Hi everyone, I hope that you helps me. I have a board with TPA3112D1 and in some board after 3-4 mins the TPA go to fault condition. If we measure temperature above the case, we measure 43,4°C and we are in a Tambient = 25°C.…
