May I ask if the Figure 86 on page 58 in ADS42LB69 datasheet shows Input resitance (Rin) not Impedance (Zin)?

Best regards,

Masa

Hi Masa,

Yes, figure 86 shows input resistance. The frequency dependence is due to the switched capacitor resistance of the input sample and hold circuit.

Thanks,

Eben.
