When disable(not use) internal DC-DC converter, I would like to ask three questions as below.
1) Is it OK that TWO AD5755 mounted PCB both side same position?
2) Does Thermal pad need ”VIA" even disable internal DC-DC ?
3) AD5755 datasheet says "θJA=28°C/W" is specified with thermal pad + VIA?
Thank you for your help in advance.
