Analog To Digital Converters (ADC) FAQ

What is the input capacitance of the ADC08351?

The input capacitance varies with the clock level: it is 4 pF when the clock is low and 11 pF when the clock is high.

How does the power-down feature work?

When the PD (Power Down) pin is driven high, the device enters power-down mode, consuming less than 7 mW. When the PD pin is low, the device operates normally.

What is the pipeline delay of the ADC08351?

The pipeline delay (latency) is 2.5 clock cycles between the initiation of conversion and the availability of the result at the output.
