I'm planning using the AD74115H combo DAC/ADC but after reading the datasheet, I have simple questions that have no obvious answers :
- Can it be used as independent regular ADC and DAC (voltage modes only, with no power, no current at all, no "screw terminal " stuff) ? The datasheet never suggest this, there is always some link between them in any case because only specific uses are covered with all sorts of sense lines which are not used at all in a "standard" use.
- If this can be used has separate ADC and DACs, which inputs and outputs are used ? For the ADC, i suppose that the SENSELF and AGND can be used as single ended inputs, but it is not that clear for the DAC : is it between VIOUT and AGND? Is the SENSEH pin has to be used? Where the CCOMP should be placed?
- If the Hart modem is not used, how the pins should be connected ?
- if the "digital" part is not used, how the related pins are connected (external MOSFETS, DO_VDD...)?
Thanks in advance,
