DC1697A is a demonstration circuit for the LTC2945 I2C power monitor. It 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 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. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. The DC1697A was designed to be connected to the DC590 and controlled through the QuikEval suite of software.
