ADS8860: query of TI precision lab - ADCs

Hongjia-Wu

Part Number: ADS8860
Other Parts Discussed in Thread: ADS8353

Hi Team,

In the slides of "Building the SAR ADC Simulation Model", what is the corresponding parameter for 10ns? Can we find related information in ADS8860 datasheet? Thank you.

Best Regards,

Hi Hongjia,

As I introduced and talked to you guys at the Plabs ADC training , this 10ns timing is used to reset the charge on the internal sample-hold capacitor of ADC at the end of cycle through the reset switch, so every time the signal on the sample-hold capacitor can be settled from the worst 0V to the highest +5V on ADS8860 ADC. This is just for simulation purpose to check the settling error on the sample-hold capacitor as the worst case.

Best regards

Dale

Hi Dale

so 10 ns is not related to the actual ADC, if using other ADC like ADS8353 for simulation, still use 10ns, right?

thanks

Hi Hongjia,

Correct.

Best regards,
