Hi,
Good Day.
Customer is currently identifying components for an application that requires an I2C ADC with 16 to 18 bits resolution, a minimum sampling rate of 80 sps (min), unipolar input voltage between 0 and 3.3V or 5V, external reference, 1 or 2 differential channel. The idea is to perform a ratiometric measurement of a high impedance (~2MOhm) resistive sensing element.
Please advise. Thank you very much.
Best Regards,
Ray Vincent
