AMC60804: ADC sample voltage of VDAC and display abnormal.

Hale Tan

Part Number: AMC60804

Hi team,

The customer use AMC60804 to drive EML. And they use ADC to sample VDAC output voltage. And when VDAC is open load, the ADC displays 0x0800. Do you know the reason?

Hi Hale,

Are they using the internal ADC to VDAC connection, or connecting the output voltage to one of the external ADC inputs? What is the VDAC output set to when they see this behavior?

Best,
