Analog Devices Inc. DC2839A Demo Circuit for the LTC6115

Analog Devices Inc. DC2839A Demo Circuit for the LTC6115 is designed to evaluate the LTC6115 high-voltage side high-current and voltage sense. This demo circuit is capable of measuring inputs up to 100V and 2A. The DC2839A demo circuit can be connected to Linduino^® as a shield and has an accompanying Linduino sketch. The voltage sense input supply can be either an external 2.7V to 5.5V power source or drawn from a Linduino (DC2026C) board when DC2839A is used as a Linduino shield. This demo circuit features a four-terminal 50mΩ sense resistor with a footprint for larger and higher-power rated parts. A 1:1000 resistor divider can be selected with jumpers to provide simulated mV-scale input difference voltages if high-currents are not available. The LTC6115 voltage and current sense can be configured to measure the same input or separate inputs.
