Frequently Asked Questions
What is the supply voltage and common-mode voltage range of the INA226AIDGSR?
The INA226AIDGSR operates from a supply voltage of 2.7V to 5.5V. Its common-mode input voltage range extends from 0V to 36V, allowing it to monitor both low-side and high-side current paths in systems with bus voltages up to 36V.
What interface does the INA226AIDGSR use to communicate with a microcontroller?
The INA226AIDGSR uses an I2C and SMBus compatible digital interface, supporting up to 16 unique programmable addresses. This makes it easy to integrate multiple monitors on a single bus in multi-rail power management applications.
What are the typical applications for the INA226AIDGSR?
Typical applications include server power management, telecom power systems, solar energy monitoring, battery chargers, industrial motor drives, and portable electronics. Its high accuracy and wide voltage range make it suitable for any system requiring precise current and power monitoring.
What package type is the INA226AIDGSR and what does the 'AIDGSR' suffix mean?
The INA226AIDGSR is offered in a 10-pin MSOP (TSSOP10) small outline surface-mount package. The 'A' suffix indicates the standard temperature grade, 'IDGSR' encodes the MSOP package in tape-and-reel form factor, suitable for automated PCB assembly.
Is there a recommended alternative or substitute for the INA226AIDGSR?
Common alternatives include the INA219 (lower cost, 26V common mode, I2C), INA231 (similar spec, different address options), and INA260 (with integrated shunt resistor). The INA226 is preferred when higher accuracy and a 36V common-mode range are required.
