A downhole electrical logging tool includes a mandrel, and a pad coupled to and radially extendable from the mandrel. The pad includes an isolated power supply configured to receive DC or AC power via the mandrel and convert the DC or AC power into one or more DC voltages for powering electronic components on the pad. The pad further includes a digital data processor (e.g., a microcontroller, field programmable gate array, or digital signal processor) powered by the isolated power supply, a transmitter electrode, and a sensing electrode. The pad also includes a housing in which the controller and isolated power supply are located, and a pad body coupled to the mandrel. Components inside the housing are electrically isolated from the pad body. The tool further includes a signal generator electrically coupled to the transmitter electrode to drive the transmitter electrode.
