Team,
How is the high impedance input (1 MΩ) affecting the SNR?
Do we have some app note that can details the benefit/drawback/trade-offs when using an ADC with high input impedance?
Thanks in advance,
A.

Hi Anthony,
The ADS8588 has an internal drive amplifier, so there is no specific need to worry about driving the low impedance input of a typical SAR converter. This app note may help: https://www.ti.com/lit/an/sbaa232a/sbaa232a.pdf
