Stacking the ADR504x.

Hi,

Examples of stacking circuit has been posted on the ADR5045 data sheet.
Please refer to Figure.21.

Figure 21a shows three ADR5045 devices configured to give 15 V.

Please refer to Figure.21.

Is it possible with reference to the figure, to generate a -0.5V using the ADR5043 (3.0V) and ADR5041 (2.5V)?

Amplifier because it causes the noise, but they do not consider it used.
Is it possible to configure only voltage reference?

    Hi Hara,

    Apologies for the delay of response. I am not actually sure about the configuration you are looking into but if you are thinking stacking the ADR5041 and ADR5043 like this to get a -0.5 V:

    This will never work and it will not give you a -0.5 V.

    If you create a 2.5 V then a separate 3 V then you can have a -0.5 V between these two nodes.

    My questions is what do you really want to do? Do you have a particular configuration that you want me to check if it is gonna work or not?

    Best regards,

    Emman
