Part Number: TPA3220 10.2.1.2 Detailed Design Procedures: "The device inverts the audio signal from input to output."
I'm assuming this applies to differential inputs. Would prefer that the amp didn't invert.
Can I put single-ended into…
Part Number: TPA3220 Hello Experts, Customer has question as follows. Would you please answer them? 1. How long does the duration time of "L" width need for device reset? 2. Do you have gain vs. frequency response graph? And also please tell variation…
Part Number: TPA3220 Hi Experts, My customer has question as follows. Would you answer them? 1. Customer measured a transient time of /CMUTE-pin while device started up. The datasheet mentioned that it is about 20ms, but the measurement result is 4~5ms…
Part Number: TPA3220 Hello Experts, I have couple of question for TPA3220. Would you please answer them? 1. RESET The datasheet mentioned below comment. "To ensure thermal reliability, the rising edge of RESET must occur no sooner than 4 ms after the falling…
Part Number: TPA3220 Other Parts Discussed in Thread: LM317 , Okay, I had the same issue with the RESET line and verified that applying an external 5V on RESET started the part. This is mentioned in the forum here. (Nick and Luis contributing.)
However…
Part Number: TPA3220 Hi, I have designed two PCBs using the TPA3220 both of which are working very well with one caveat
I have to make sure that the source driving the amplifier PCB is isolated in terms of its power supply or I get some horrible high…
Part Number: TPA3220 Dear Sirs,
My customer asked us about open load detection for TPA3220.
He asked us that if opening or disconnection occurs at the speaker output side, whether TPA 3220 can detect it.
Does TPA3220 has open load detection?
I checked…
Part Number: TPA3220 Dear Robert / Adam,
I have come across what seems to be conflicting advice in the TPA3220 evaluation module vs the slaa701a application note.
The TPA3220 uses AD modulation. In page 8 of slaa701a, it says:
For class-D amplifiers,…
Part Number: TPA3220 I'm trying to use the internal LDO in the TPA3220 and I must be doing something really silly as I can't get it to work
I am feeding the same voltage to the VDD (pin1) as I am into the PVDD pins - 30V
I have disconnected AVDD…
Part Number: TPA3220 Dear Sirs,
My customer asked us about FAULT/OTW voltage at open condition of TPA3220.
He measured voltage of FAULT/OTW pins of tpa3220 at open condition .
As a result, the voltage was 5V.
Although the description below is on page…
