Part Number: TPA3144D2 Hi team,
1. Our usage scenario has two speakers 2W/8Ω, THD+N 10%.
2. In the above usage scenario, what is the minimum voltage of PVCC and AVCC of TPA3144D2PWPR? How to configure the resistor value of LIMRATE/GAIN/LIMTHERS…
Part Number: TPA3144D2 Other Parts Discussed in Thread: PCM2900C , PCM2900 Hi everyone!
I designed a board that among other things uses a TPA3144D2 to drive a pair of 8Ω / 2-watt speakers. The source for the audio is a PCM2900C audio codec.
It's configured…
Part Number: TPA3144D2 Dear TI, I have a design based on the TPA3144D2, I have implemented a diagram that resembles figure 26 in the datasheet (SLOS907C – APRIL 2015 – REVISED DECEMBER 2017). I operated it on a 12V supply (always applied) and a 8 ohm…
Part Number: TPA3144D2 Hello:
TPA3144D2 has a design method to describe the inductance of output filter in datasheet. If using alternative Bead inductance in use process, if you can use the inductance calculation?

Part Number: TPA3144D2 Hi Sir,
My customer suing TPA3144D2 buy can hear speaker has a little "zi zi " noise in special music. The o/p is using bead +C.
'Zi Zi" noise will gone if change to using LC filter. Do you know what possible reason cause the…
Hi Nidhi,
How much is the speaker resistance in this case? Even you use 4ohm load, the max output power(THD=10%) is ~3.3W with 5V PVCC, please refer to the Figure 14 in the datasheet. With 4ohm load, the PVCC has to be higher than 6~6.5V to support 10…
Part Number: TPA3144D2 Please let me know about three points below for TPA3144D2 maximum rating.
①Datasheet page 5 is not described maximum rating of GVDD (Blank).
Is there test data for GVDD maximum rating?
Or, I guess that GVDD rating is 20V…
Part Number: TPA3144D2 Other Parts Discussed in Thread: TPA3136D2 , TPA3140D2 Dear Sirs,
My customer asked us about Radiated Emission of TPA3144D2.
I would like to compare the data of Radiated Emission at FFM and SSM. Do you have Radiated Emission…
