Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi support team all.
Datasheet page 16 8.2 Typical Application In the application circuit, a 100uF capacitor is connected to the PVCC terminal. (Red frame)
(1) Is this capacitor a ceramic capacitor? Or is it a polarized electrolytic capacitor?
(2) Is…
Part Number: TPA3112D1-Q1 Tool/software: 1. Can the voltage values of PVCC and AVCC be different? PVCC uses the filtered vehicle power supply of 9~16V, is it OK to use a constant 5V power supply for AVCC? What is the purpose of the connection between…
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 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 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 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…
