Product data sheet
The integrated input buffer offers the following advantages:
The sample phase occurs when the internal clock (derived from the clock signal on pin
CLKP/CLKM) is HIGH. The voltage is then held on the sampling capacitors. When the
clock signal goes LOW, the stage enters the hold phase and the voltage information is
transmitted to the ADC core.

The kickback effect is avoided - the charge injection and glitches generated by the
S/H input stage are isolated from the input circuitry. So there’s no need for additional
filtering.
The input capacitance is very low and constant over a wide frequency range, which
makes the ADC1415S easy to drive.
