Other Parts Discussed in Thread: REF5050,
Dear Technical Support Team,
I use DAC80502 with REF5050.
Expected output voltage of REF5050 is 5V, however it shows 2.5V.
I tried to change external reference mode (disable internal reference: Address:0x30 data 0x0100).
However it doesn't change 5V reference correctly
Input voltage of REF5050 is 10V and I can see it with oscilloscope.
①
How do I improve 5V output. See attached schematic.
②
Can I read the register value with SPI mode?
Now I tried to write register such as Fullscale(Reg 0x08 , 0xFF ) , however output doesn't change from 0V to 5V.
Best Regards,
