Part Number: TPA3112D1 My customer is not able to get the same answers from the equation 1 that are in Table 2.
I am trying to replicate their calcuations - but I don't see what number was used for RS.
Can you clarify how you arrived to the numbers…
Part Number: TPA3112D1 Hi Team,
Issue: the IC will be heated and broke fast with power on. Please find the schematic in the below.
Questions:
-Could you please help review the schematic and give any suggestion to improve?
-I assume that the issue may…
Part Number: TPA3112D1 Hi, I'm having problems getting this amplifier to work , in that on power up It goes into fault.
Power supply = 12V
Speaker = 8R
I've removed all input cct and grounded inputs Via 1uF caps
There are no shorts nor o/c's,…
Part Number: TPA3112D1 Hi,
/FAULT pin is asserted to low if shorting the speaker terminal after LC filter to PVCC or GND, but /FAULT pin isn't asserted to low if shorting both speaker terminals when inputting 1kHz. So, the output current exceeds 9A.…
Part Number: TPA3112D1 Hi team,
My customer will use TPA3112D1 and provided some questions regarding PMIM as follows
In section 7.3.3 PLIM, datasheet states that "The PLIMIT circuits sets a limit on the output peak-to-peak voltage. ~ This virtual…
Part Number: TPA3112D1 Other Parts Discussed in Thread: TPA3111D1 Hello,
My customer is facing problem on the target board.
The device should be shout down when speaker output OUTN and OUTP are shorted. but over current protection doesn't work at the…
Part Number: TPA3112D1 Hi I am in need of some help in minimizing EMC and conducted emissions. The TPA3112D1 is a Class D Audio Amp that has its output switching at approx 310kHz. My aim is to reduce the amplitude of the fundamental and harmonics that…
