    what does switched-current ADC mean? Is it similar to ADC that is operated by current mode?

    Hi,

    The ADC uses a comparitor internally. The external voltage drives a current through a resistor, and that current is finally matched by a current of opposite sign controlled by the electronics inside the ADC. The internal current usually comes from an R - 2R ladder, and increases in steps until the comparitor indicates either a balance or overrange. The current steps are the switched current part of the ADC.

    hi,
    Definition of Inductance:
    A property of a conductor or circuit which resists a change in current. It causes current changes to lag behind voltage changes and is measured in henrys.
    thanks!
