Packages The LTCВ®2992 is a rail-to-rail system monitor that measures current, voltage, and power of two supplies. It
features an operating range of 2.7V to 100V and includes
a shunt regulator for supplies above 100V. The voltage
measurement range of 0V to 100V is independent of the
input supply. Two ADCs simultaneously measure each
supply’s current. A third ADC monitors the input voltages …
