DC2156A

Demonstration circuit 2156A features LTC®2946 rail to rail system monitor that measures current, voltage, power, energy and charge. It features an operating range of 2.7 to 100V and includes a shunt regulator for operation from supplies above 100V to allow flexibility in selection of input supply. The current measurement range of 0V to 100V is independent of the input supply. An onboard, 0.4% accurate, 12bit ADC measures load current, input voltage and an auxiliary external voltage. A 24bit power value is generated by digitally multiplying the measured 12bit load current and input voltage data. Energy and charge data are generated by integrating power and current. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. The DC2156A was designed to be connected to the DC590 and controlled through the QuikEval™ suite of software.
