LTC2945 Demo Board | Wide Range I2C Power Monitor (requires DC2026)

Analog Devices Inc.

Demonstration circuit 1697A features the LTC2945. The LTC2945 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 common mode 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 generated by digitally multiplying the measured 12-bit 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. Data is reported via a standard I2C interface. The demo board is populated for a 5A application. This can be changed by populating R1 accordingly.
