Part Number: TPA2080D1 Hello,
What would happen if the switching inductor (2.2uH in the application schematic of the datasheet, fig 24) were to fail or if it was not soldered at all? Would the TPA2080 be in an unstable state with potentially a high current…
Part Number: TPA2080D1 Dear TI Team.
I would like to hear the advice of TPA2080D1 because of POP noise during TEST.
Please refer to the following circuit.
Due to Fixed Gain, we have to reduce the input and add the resistor as above.
POP noise is generated…
Hi Chun,
I noticed this device has 20dB fixed gain. I did the test with the conditions required, but I got an output voltage of 3.8Vrms with an input voltage of 400mVrms. The voltage gain has a range around 19.5dB to 20.5dB.
Best Regards

Part Number: TPA2080D1 SCH-WSS_BM20L-V02.pdf TPA2080D amplifier problems are as follows: 1, when the volume is up to the maximum, the distortion is relatively large 2. When the volume is up to the maximum, the IC works very hot 3. When the volume is up to…
Other Parts Discussed in Thread: TPA2080D1 Hi Team,
customer platform is based on Qualcomm PM8952 and they adopted the TPA2080D1 to drive the speaker, attached is their TPA2080D1 schematic, they want to check with BU to see if any design concerns on this schematic…
Other Parts Discussed in Thread: TPA2080D1 Hi Team
We are looking for low thickness for the power inductor (2.2uH) for TPA2080D1
What is the max current of inductor(2.2uH) ? 700mA ?
SPEC page 5 have show IBOOST = 700 mA
[ TPA2080D1 ] Current Limit
Hi,
IL (average inductor current) has three different current limit specifications as table below. Can you help me to understand the difference? Specially, " Boost converter starts up from full shutdown, 600mA " and "…
Other Parts Discussed in Thread: TPA2080D1 Hi Sir
As mentioned in the section “ Speaker Load Limitation”
A portion of speaker load current can flow back into the boost converter output via the Class-D output H-bridge high-side device. This…
Other Parts Discussed in Thread: TPA2010D1 , TPA2080D1 Hi Sir
An specification, “Maximum Input Voltage = 2Vrms (Typ) @ EN = 0 ” listed in electrical characteristics.
Since EN = 0, device is inactive, and 2Vrms = 2.828Vpeak that is not beyond…
