INA233AIDGSR

Current Regulation/Management Overview

The INA233AIDGSR is a current sense amplifier from Texas Instruments featuring 16-bit precision and I2C/PMBus interfaces. It operates with a common-mode voltage range of 0 V to 36 V and supports supply voltages between 2.7 V and 5.5 V. Key electrical parameters include an input bias current of 8 µA, input offset voltage of 10 µV, and CMRR of 140 dB. The device draws 310 µA of operating current, offers a gain error of 0.1%, and functions within a temperature range of -40°C to +125°C in a surface-mount package.

Current Regulation/Management Feature Summary

• Provides high-precision current monitoring with integrated digital output capabilities via standard communication protocols.
• Supports both high-side and low-side sensing configurations across a wide common-mode voltage range.
• Delivers ultra-precise measurement performance with minimal input offset voltage and bias current.

Current Regulation/Management Applications

• Industrial process control systems requiring precise current feedback
• Power management units in computing infrastructure
• Battery management systems for accurate state-of-charge estimation

Current Regulation/Management Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm the 'AID' designation matches required accuracy and temperature grades. Ensure compatibility with existing I2C or PMBus controller logic levels. Check for recent production change notices affecting assembly sites or materials. Validate that the 10-VSSOP footprint aligns with the target PCB design constraints.

Current Regulation/Management Selection Notes

Select this component when high accuracy and digital integration are prioritized over discrete solutions. Consider the 16-bit resolution for applications demanding fine current step detection. Evaluate the 36 V common-mode range against system rail voltages. Assess power budget requirements given the 310 µA quiescent current draw. Compare interface flexibility against simpler analog-output alternatives if protocol support is not needed.

Current Regulation/Management Part Context

This part belongs to the INA233 family of current, voltage, and power monitors. It complements other Texas Instruments sensors by offering combined measurement capabilities in a compact form factor. The series targets modern embedded systems where space and precision are critical constraints.
