I don't think so, for the reasons that I mentioned previously. You need one of our class D (or AB) Piezo drivers like the TPA2100P1.

Hi Ashwak,Welcome to the forum! The ADS1248 takes a differential measurement from one analog input to another. It is not clear how you are connecting your inputs, so if you send me your schematic it...

Hi Melanie,Thanks for the explanation!Therefore, a single-ended measurement should use the REF_ELEC as the negative input to all of input channels. This can be done by routing REF_ELEC to the SRB1 pin...
