DAC7760: DAC7760

Satyanarayana Keetha
Prodigy 10 points
Part Number: DAC7760

Tool/software:

 I am facing with finding 0- 10V output at Vout for our Design board.

The following configuration done.

WriteSingle_DAC7760(0x56, 0x0001)

WriteSingle_DAC7760(0x55, 0x9001)

WriteSingle_DAC7760(0x57,0x0300)

 

After that

WriteSingle_DAC7760(0x01,0xFFF0); //Write DAC Data register

I have configured for 10v. But getting 5volts.

Could you please help me on this

    Hi, 

    On my EVM, after I write to the Control Register (0x55), I am seeing 5 V on the output (which makes sense as it is configured to default to midscale for a unipolar range).

    Once I update the DAC Data Register, I immediately see 10 V, so your commands look right.


    Are you using the DACx760EVM? If not, can you provide your schematic?

    Can you also readback each register after writing to verify they were written to correctly?

    Thanks,
    Lucas
