Part Number: TPA3223 Tool/software: Dears,
Is there a good solution to the problem of an impact sound when the RESET pin controls the high and low levels? When it comes to controlling RESET We also need to control CMUTE, mainly this issue.
Schematic…
Part Number: TPA3223 Other Parts Discussed in Thread: TPA3250 , TPA3251 Tool/software: Hi all,
i'm facing an unexpected oscillation issue with my TPA3223 Design. First of all, the overall System Description, basically the amp is integrated onto "all…
Part Number: TPA3223 Hi, we expereinced different behaviour of the CLIPn signal if the TPA3223 is held in RESET. In one setup we see that the CLIP is HI (not reporting clipping) and in another setup the CLIPn remains lo (CLIP asserted) and only rises…
Part Number: TPA3223 Tool/software: Hello,
Our customer is verifying TPA3223 clipping waveform manner while over drive the D-amp.
Condition is PVdd=30V 4ohms load, LPF inductor has 16A current handling.
It seems this working condition is much…
Part Number: TPA3223 Other Parts Discussed in Thread: LM5122 , Tool/software: I am making a two-channel amplifier with the TPA3223 (100 W into 11 ohms each channel). It also has a 2-phase boost converter, using two of the LM5122, to create a 36-volt supply…
Part Number: TPA3223 Tool/software: I had designed the audio amplifier and during testing I faced this issue. The IC as well as the output filter inductors heats up even when there is no audio input. I tested the amplifier at 36V and also at 42V DC but…

Part Number: TPA3223EVM Tool/software: Can you send me the altium design file for the evaluation board? And is it ok to design such boards in just two layers?
Part Number: TPA3223 Tool/software: Dear Sir,
We heard the PoP noise when the TPA3223 went into Mute function and discovered the possible problem when measuring the TPA3223 output waveform. The problem seems to be caused by the voltage difference across…
Part Number: TPA3223 Tool/software: Hello
I'm trying to build a simple small signal model of a self oscillating class D amplifier. Obviously the most challenging part is modeling the switching part from the comparator to the power stage. I found a few…
