Hi Gokul,
The layout / schematic look fine.
Any chance you can try a higher frequency XTAL or some sort of external differential clock source to debug the board otherwise?
How are you looking for the XTAL oscillation - Are you putting a scope probe…
Hi Yuan,
For the devices I'm familiar with (LMxxxx Part Numbers), we don't have a suitable solution.
I'd have to defer the answer to other E2E participants to see if they can offer a solution to your low frequency ultrasound problem.

Hello Martin,
Yes, I looked to see if I can find any data which explores what "typically" occurs when your input CM voltage is less than the minimum specified, but I could not find anything useful.
Lacking any other data, I'd recommend to stay on…
Hello,
Here is a discussion on power dissipation / heat / temperature-rise / thermal resistance related to the LM98725 which is a higher power device than the LM98722, but it may apply as well:

Hi Dmitrijs,
Sorry to hear that you are having problems.
Output impedance of LM96550: The output impedance is shown in the datasheet (Output ON Resistance) as 7 to 11 ohm.
Malfunction of LM96550 : Did you make sure that you followed the instructions…
