1 System Introduction

This document discuss an application of a single-phase AC power monitor using a simple, low-cost Texas Instruments MCU MSPM0C1104. The MSPM0C1104 is a mixed signal microcontroller that integrates with a 12-bit SAR ADC for voltage and current sensing and UART communication interface to communicate with the GUI that running at PC. TLV9062 also a low cost two channel OPA that to used for the current and voltage differential signal sensing. (Also can just used a MSPM0L1304 include two internal OPAs)
