ADS7828: Input impedance

Kuramochi Tadahiko

Part Number: ADS7828

Hi,

Though input leakage current is specified on the datasheet, does it depend on input voltage?

If yes, I would like to know it in the case VIN=0V and 1.8V.

SCL is mentioned 100kHz or 400kHz.

Best Regards,

Kuramochi

    Hi TQ San

    We do not have the data on leakage current for your conditions. Having said that, the device leakage current will be well within the datasheet limits for specified input range in datasheet (Analog input from 0 to VREF).

    Can you please let me know why do you need this data. What is the application for this device. Does the leakage current spec affects the system performance?

    Thanks & Regards
