• RE: Interfacing DC682A (Demo Board for the LTC1859) with Arduino Mega

    Yes, ground channels 1-7 if they are not being used.

    Vref drives the REFCOMP buffer (See Figure 3 of the LTC1859 data sheet), so it should not be grounded.

    Is the input voltage on CH0 and COM referred to the DC682A ground? If not the voltage may be floating…

  • LTC1859 DC performance result

    Hi ADI Expert,

    I need your help to clear of LTC1859 some questions from datasheet.

    According to the datasheet page13, Figure 5. Histogram for 4096 conversions. The DC PERFORMANCE result is tested by internal Vref 2.5V or external Vref?

    I saw AVDD and…
