Overview

Product Details

The DC2369A demo circuit is a reference design that implements a wireless current sense solution using Analog Device's low power integrated circuits. The only external connection needed is the current to be measured, allowing this circuit to be inserted at any voltage level or isolation level.


The design combines components for current measurement, power management and wireless mesh networking. A micro-power zero-drift op amp (LTC2063) amplifies the voltage across a sense resistor. A 16-bit SAR ADC and precision reference (AD7988 and LT6656) digitize the reading. A SmartMesh IP wireless radio module (LTP5901-IPM) runs the application, provides the wireless mesh connectivity and communicates with a central network manager. A switching power supply (LTC3335) counts the cumulative charge drawn from the included battery while also regulating the output voltage for the rest of the application.


The DC2369A can be easily added to the DC9021B SmartMesh IP Starter Kit, or any SmartMesh IP network.
