INA138NA/3K DEMO

Overview

This project is a solution verification board used to verify the current monitoring chip/INA138NA250 (mall number C133804) of Lichuang Mall. This project is a solution verification board
used to verify the analog-to-digital conversion chip/MCP3421A0T-E/CH (C29454) of Lichuang Mall.
The project is used to verify the solution verification board of Lichuang Mall precision operational amplifier/OPA340NA/3K (C73479). The

project verifies 2 pieces of TI's ina138 current acquisition chip. After the bidirectional current is collected and buffered by MCP340, it is collected by Microchip's ADC mcp3421. It is transmitted to the microcontroller MSP430RF2433 and sent to the host computer serial port assistant after simple filtering!
