Part Number: TPA3220 Tool/software: We design TPA3220 work on BTL mode(SCH as below) , but each day first time power up , TPA3220 go into PBTL mode, retry power up again , TPA3220 go into BTL mode .
If the machine is turned off for more than 1 hour,…
Part Number: TPA3220 Tool/software: Hello,
I have an application for driving a Piezoelectric transducer that requires a high power sine wave excitation at frequencies as high as 40Khz. The data sheet has some plots for distortion and noise up to 40Khz…
Part Number: TPA3220 What exactly are the differential and single-ended input impedances for the TPA3220?
The August 2018 data sheet section 9.3.5 quotes impedances of 48k, 24k, 12k, and 7.7k depending on gain selection. It also suggests, but does not…
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
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

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 shows…
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 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. We want…
