I had some problems testing the PCB board made by ADN8834 and hope you can help with it.
I made PCB boards based on the ADN8834CP-EVALZ evaluation board schematic,and with NTC, no TEC, Vvtec was at 1.25V. stating that LDR and SFB have no output and the truth.
But the actual Vout1 output varies according to the NTC resistance value, and the Vout2 is also changing.on the basis of
The LDR and SFB should have an output while I checked that the VDD input is 5V.
I don t understand why there is no output.Can you help me.
