Introduction

The INA219AIDCNR is a current shunt and power monitor with a 12C- or SMBus-compatible interface. This blog will introduce INA219AIDCNR systematically from its features, pinout to its specifications, applications, also including INA219AIDCNR datasheet and so much more.

INA219AIDCNR Overview

The monitor INA219AIDCNR both shunts voltage drop and buses supply voltage, with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts of current in amperes. An additional multiplying register calculates power in watts. The INA219AIDCNR is available in two grades: A and B. The B-grade version has higher accuracy and higher precision specifications.

The INA219AIDCNR senses across shunts on buses that can vary from 0 to 26 V. The device uses a single 3- to 5.5-V supply, drawing a maximum of 1 mA of supply current. The INA219AIDCNR operates from- 40°C to 125°C.
