Dear team
I would like to use the MA5302 to create a single-supply, single-ended input stereo amplifier.
There was an evaluation board for MA5302 with positive and negative power supplies and single-ended input, but this does not seem to be compatible with a single power supply.
Therefore, I am thinking of creating a circuit for 2 channels using the evaluation board below as a reference.
https://www.infineon.com/cms/jp/product/evaluation-boards/ref_ma5332btlsps/
I have two questions regarding the above.
① Does the supply voltage need to be +40V?
Since I only need to be able to get an output of about a few tens of W, I would like to first make a simple evaluation using a commercially available switching power supply.
(If possible, we would like to be able to evaluate by inputting 30V or less.)
② If I use a single power supply, do I need to make the audio input differential?
I would like to use single-ended input if possible.
Best Regards,
TOMMAT

I am interested in the evaluation board linked below.
https://gansystems.com/newsroom/500w-heatsinkless-audio-amplifier-from-axign/
Is it possible to order this evaluation board?
Or if you have any design information such as reference designs, please let me know.
I also have a question regarding another product.
I would like to know the difference between MA5302/MA5332/MA5342.
These are products with very similar specifications, but is it correct to understand that the optimal impedance of the driving speaker is different?
Best Regards,

Show LessHello,
I have a project that needs to have a frequency connection that takes place at 5”. This connection will complete a circuit.
What is the best way to do this? Will it be easiest to limit the transmit power and wait for a frequency connection to be detected? This would be easiest with an RFid transmitter I’m sure.
Would it be easiest to have a constant frequency connection between the two components that activate the circuit once the frequency strength reaches a certain strength? I want the tots enclosure to be no more than 1”x1”LxW and .5” in H
I want the simplest most reliable connection method that allows for an activation of a circuit without fail. Please let me know what you think. Call or email me. Thank you.

Hello! I want a development board for TDA5230/TDA5231! Do you have PCB board diagrams and component models? Or there are development boards for sale! Also, what is the connection between the development board and the computer host! Where do I get the devices that connect to the computer from?

Show LessIs any possibility, to detect RX transceiver on a E1 multiframe structure channel shifted? and if so, is someway to synchronize TX according to channel shifted?
For example, in a E1 32-channel frame, channel 00 is the synchronization, but there is a particular system that synchronization channel is assigned to channel 01.
Many thanks.
