Hi TI team,
Thank you for your support.
1. Is this board ROHS3 Directive (EU) 2015/863 compliant?
2. If so, Can you provide RoHS certification for this part?
Kind Regards,

Part Number: DEM-OPA-SO-1A FOR EVAL BOARD : DEM-OPA-SO-1A, WE REQUIRED BOM TO BE POPULATED ON THE PCB WITH SCHEMATICS, ASSEMBLY INSTRUCTIONS AND TESTING PROCEDURE AS PER DATA SHEET.
Part Number: DEM-BUF-SO-1A Hi Team,
A customer has this board but they are having 10x attenuated output and not unity gain.
The board was assembled as per the schematic with the corresponding value:
Rin1 = 50 ohms; Rin2 = 25 ohms; Rout 1= 50 ohms; Rout2…
Hello Niklas,
thanks for your feedback. First I will answer your question:
- Is the device set to DEM or FPWM mode? -> FPWM (MODE via 10k pulled to VCC) - The LM5122 HO signal is measured with reference to GND, so it mostly shows the SW, correct? -…
Hi Bob,
We add the 1Kohm push up to 1A and 1Kohm push down 1B and the problem is solved, so many thanks for your and Clemens' support;
Now we have a suspicion that the voltage state as below screenshot , so the output voltage is indefinited;
We will update…
for 1: Vbb is needed even if for AC coupled, so R49 is still needed , ( looks I replied wrong last time.)
for 2: you can DNI R13/R14, R21, R22, R23, R24, R25, R26, R27 and R28.
Also remove external bias.
There are two 50ohm inside 1A/1B and biased by…
Hi Sakamoto-san,
I looked through your registers and it seems that you did not "turn on" your output channels, so maybe the device is only turning on DAC channels 1 and 3. Try to power up all enabled DAC channels after setting CH_EN. To do this…
