Part Number: TPA3118D2 Motorola Solutions would like to add a DC blocking capacitor directly at the Audio PA output of the TPA3118D2. The idea is to eliminate the 6.8V DC bias to keep the pre-amp, simplifying their factory and repair processes. Based…
Part Number: TPA3118D2-Q1 Other Parts Discussed in Thread: TAS5441-Q1 Need an audio amplifier that accepts analog L/R audio input from a headphone output to drive a 20W, 4 ohm single speaker. Is something like the TPA3118D2-Q1 the best choice for this…
Part Number: TPA3118D2 Other Parts Discussed in Thread: PCM2912A , SCH_USB_2-Audio_2026-03-15.pdf
The attached file contains my circuit schematic. Please note that the Analog Ground (indicated by the triangle symbol) and Digital Ground (GND) are connected…
Part Number: TPA3118D2-Q1 Hi TI-team
what's the turn-on time of MUTE from the falling to waveform out when SD is High.
when there are no signal in, we want the amplifier keep silent, MUTE=High, SD=HIGH
hope the amplifier can fast response to the…

Hi TI.
I set the PLIMIT to 0V (shorted it to GND) while it (PLIMIT) is connected through a 51k oHm resistor to GVDD. I expected it will limit the Pmax to 0W (no sound) but it's still playing. Do you have any…
Part Number: TPA3118D2-Q1 Dear team,
Would I know the layout requirements for heatsink less system? We understand the thermal issue is not only IC but air flow or etc. and system design matter. But please help us to understand it more.
Q1: D/S mentions…
Part Number: TPA3118D2 Tool/software: Hello
In our application we planned to use TPA3118D2, but just now noticed that it has a DC protection feature disabling the IC at very low AC frequencies. While such feature is beneficial in audio applications…
Part Number: TPA3118D2 Tool/software: Hello
I noticed that in TPA3118 DS the same bulk capacitance is used in SE and PBTL modes in the typical application example.I would guess that PBTL requires much less capacitance on the power supply. Could you…
Part Number: TPA3118D2 Tool/software: Hi,
We have qeustion about TPA3118D2 in standby there still have high power consumtipon.
Below figure 1 is meansure on EVM, is it normal? Why have sinewave on input pin?

Part Number: TPA3118D2 Other Parts Discussed in Thread: PCM5100 Tool/software: I designed a Digital Audio circuit with the TPA3118D2 as the audio amplifier.
It's using a PCM5100 as a I2S DAC which is connected to the TPA3118. I've attached the parts…
