Part Number: TPA3123D2 Hello,
I am using the TPA3123D2 in a single-ended (SE) configuration, with speakers connected between R-OUT and GND, and between L-OUT and GND. I confirmed that both the R-OUT and L-OUT output signals are inverted by approximately…
Part Number: TPA3123D2 Hello,
We are currently evaluating the TPA3123D2EVM to verify the IC’s operation. While checking the gain and frequency response, we observed an unintended gain increase of approximately 50 dB around 250 kHz. We would like to…
Part Number: TPA3123D2 Hi,
I am using TPA3123D2PWPR amplifier in my design. Please review the attached schematic. This amplifier is intended for driving a passive speaker 2W, 8ohm. The output expected is 2.83Vrms with supply voltage of 24V.
Thanks…

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 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 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…
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…
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
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…
