Part Number: TPA3123D2 Hello,
We have an existing design which uses the TPA3123D2 but need to verify the signal inputs it can tolerate. We supply all VCC from +24V and all GND are at the same 0V potential. I note the absolute maximum input voltage is …
Part Number: TPA3123D2 Other Parts Discussed in Thread: LM675 , OPA548 , TPA3118D2 Hi Expert,
My customer is considering the signal amplifier with D-amp (not audio)
Input 0 to 3.3V （Trapezoidal wave, Tr=Tf=10us）
Output 0 to 24V
Load condition
RC x 1…
Part Number: TPA3123D2 Hi team
MPN;TPA3123dD2 Detailed description: when Ti demo board is used for debugging, there are several problems:
1.24v power supply and 4 Ω load. When the output power reaches more than 20W, the output will have the same sound…
Part Number: TPA3123D2
First off, I need to apologize up front for a somewhat obscure question since my hands are sort of tied. But as others have experienced, I've seen the issue (TPA3123 hot at power up) pop up a few times in the forums.
The problem…
Part Number: TPA3123D2 Dear Specialists,
My customer'd like to know shutdown response time.
I would be grateful if you could advise.

In the data sheet, about the response time of the mute pin, it is stated that a waiting time (Δt) of 120 ms is…
Part Number: TPA3123D2 Hi team,
The datasheet says that the mute pin has a delay of 120ms when switching, but if it is switched at a high speed (e.g. 100ns), what will be the effect on the IC?
Sincerely. Ryu.
Part Number: TPA3123D2 Hi Team,
We used schematic on page 1 of the datasheet, but it has the problem of inductance whistling at its output. The higher the current is, the louder the sound is. The frequency of the whistling is the same as that of the output…
Part Number: TPA3100D2 Other Parts Discussed in Thread: PCM1770 , TPA3130D2 , TPA3129D2 , TPA3123D2 Tool/software: We need speaker amplifier with synchro input for PWM switching frequency 781.25 kHz or 390.625 kHz.
TPA3100D2 includes SYNC input, but it…
Part Number: TPA3123D2 We have found that the amplifier will get HOT following power-ON cycle without any audio being passed through the part.
It seems to be in some unstable state with it consuming an extra 2-Watts of heat without audio.
When cooled…
Part Number: TPA3123D2 Dears Sirs, I have a problem with TPA3123D2 amplifier. It worked ok, but at this moment when I rise input signal level, the output is cut-off, current consumption latch in 170mA and the chip start hot. I thought the speakers was…
