we have purchased EVAL-ADXL354BZ for our project work.
we are trying to give power supply to the device but please advice us regarding pin configuration, for both analog and digital supply and output through Z out.
We have referred connection diagram we are bit confused with digital and analog supply connection.
Please guide us as soon as possible.
Thanks and regards

Hi Harshitha H P,
Thank you for your use of ADXL354.
You may connect VDD and VDDIO to the same supply, with a voltage source between 2.25 V to 3.6 V.
The V1P8ANA and V1P8DIG serves as a voltage reference to the microcontroller that you plan to interface ADXL 354 with (for example, connecting V1P8ANA to VREF of Arduino provides that V1P8ANA/2 = 0 g bias output).

Hope this answers your question.
Although we have connected as per your instructions, we are not getting the output what else we can do?
Should we use both ST1 and ST2 to get the output at zout. Where should we observe the output of ST1 and ST2. Please guide us as soon as possible.
To know more about your issue, could you please send me a rough schematic of your connections? Thank you very much.
