    Packages The LTC®2945 is a rail-to-rail system monitor that measures current, voltage, and power. It features an operating
    range of 2.7V to 80V and includes a shunt regulator for
    supplies above 80V to allow flexibility in the selection of
    input supply. The current measurement range of 0V to
    80V is independent of the input supply. An onboard 0.75%
    accurate 12-bit ADC measures load current, input voltage
    and an auxiliary external voltage. A 24-bit power value is ...
