1. An analyte monitoring assembly, comprising:

  • an analyte sensor having a portion configured for transcutaneous positioning in fluid contact with interstitial fluid, the analyte sensor configured to detect an analyte level; and

    a data communication unit including an analog interface operatively coupled to the analyte sensor and configured to receive one or more signals associated with the analyte level, the data communication unit configured to communicate one or more data corresponding to the one or more signals associated with the analyte level, the data communication unit further including a peak detection unit configured to detect a condition associated with a power source of the data communication unit;

    wherein the peak detection unit is configured to electrically isolate the power source of the data communication unit from the analog interface and to provide power to the analog interface when the condition associated with the power source is detected.
