Part Number: TPA3220 I'm designing a system that will use four TPA3220s in PBTL mode. I'm planning to configure them as slaves and supply an external clock on the OSCx pins, so I can fine tune the PWM frequency and have some insurance against EMI surprises…
Part Number: TPA3220 Other Parts Discussed in Thread: TPA3223 , , TPA3250 It seems that TPA322x and 325x series are quite overlapping in parameters and performance. What is a basic guide to select proper IC for a specific application? Thanks

Hi team,
My customer found the behavior that TPA3220 output jump up when it is reset.
This is not only 1 product but all product they have, thus it should be product specification.
Please refer to the attached image. Red circle…
Part Number: TPA3220 Hi,
in datasheet "AVDD" is connect to +5V and "GVDD" is connect to CRC filter (1uF-3R3-1uF) at +5V, but in EVM "AVDD" is connect to CRC filter (1uF-3R3-1uF) at +5V and "GVDD" is connect to +5V
What is the correct layaut?
Thanks…
Part Number: TPA3220 Other Parts Discussed in Thread: TPA3255EVM Hi Team,
The spec is show TAS3220 can support 100W, but to be burned out at 20W testing, please help suggestion, thanks!

Part Number: TPA3220 Hi,
when the AC is off , there is POP sound. We added the mute control circuit, but whenever we put /CMUTE low, the POP sound would come out. There are two problems:
1. Why does /CMUTE turn low to make POP sound?
2. How to solve…
Part Number: TPA3220 Hi team，
The attachment is the principle diagram of the circuit, which is described below. I am very honored to be able to get your technical support. Below I will describe the problem and attach the corresponding circuit and parameter…
Part Number: TPA3220 Dear Sirs,
I have a project named CEXD-AEIAVB01 and implement the TPA3220 (Output Configuration BTL) for two speakers. Each speaker is 12W, 8ohm.
The PVDD is 12V. The GVDD, AVDD and VDD are 5V. Please see the screenshot below…
Part Number: TPA3220 Hi
As a hobby project I am designing automotive audio amp based on TPA3220 D-class amp. What is often happening with this automobile audio stuff is that speakers have quite low impedance (2 ohms or even 1 ohm). I have no concerns…
Part Number: TPA3220 Good Day,
I have a TI TPA3220 on a custom board along with a TPA3220 Micro Eval kit. The issue that I have been seeing is that in the default pull up state, the value is not the 3.3V as stated but actually 3.9V. It seems as though…
