I have some logic in Google Excel related to the integration with the Nova Poshta API and the Turbosms API. Overall, everything works fine, but some functionality needs to be added. All details will be discussed in correspondence. I will provide access to the Excel and the code. It is essential for the performer to have experience working with Google Excel JS in Apps Script.

Без буфера, вхідний ланцюг (конденсатор, резистори дільника) має певний імпеданс, який разом з вхідною ємністю ADC утворює ФНЧ. Частота зрізу цього фільтра може бути нестабільною через змінний вхідний імпеданс ADC. Крім того, сам ADC може вносити спотворення через свою нелінійну вхідну ємність.
Тому як мінімум потрібно використати OPA1652 як буффер
