INA230AIRGTR

Current Regulation/Management Overview

The INA230AIRGTR is a current sense amplifier from Texas Instruments designed for high-precision digital monitoring applications. It features a wide common-mode voltage range of 0 V to 36 V, allowing operation in both high-side and low-side configurations. The device integrates a 1 V/V gain with an open-drain output suitable for direct interfacing with microcontrollers or ADCs. Key electrical specifications include a maximum supply voltage of 5.5 V, a minimum of 2.7 V, and a quiescent current of 420 uA. It offers a CMRR of 120 dB, input bias current of 100 pA, and input offset voltage of 25 uV. The component operates within a temperature range of -40°C to +125°C and is housed in a 16-VQFN package.

Current Regulation/Management Feature Summary

• Supports high-side and low-side current sensing across a wide common-mode voltage range.
• Provides precise measurement capabilities with high common-mode rejection ratio.
• Features an open-drain output interface compatible with standard digital logic levels.

Current Regulation/Management Applications

• Digital power monitoring systems
• Battery management systems
• Industrial process control equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix 'RGTR' corresponds to the reel packaging configuration required for your assembly line. Confirm that the operating environment remains within the specified -40°C to +125°C thermal limits. Ensure the system's common-mode voltage does not exceed the 36 V absolute maximum rating. Check for moisture sensitivity handling requirements during storage and reflow soldering processes.

Current Regulation/Management Selection Notes

Select this component when high accuracy is required for current monitoring in systems with varying common-mode voltages. The 1 V/V gain simplifies signal conditioning by eliminating the need for external amplification stages. Consider the 16-VQFN package size if board space is constrained. Evaluate the 420 uA quiescent current against total system power budgets for efficiency optimization.

Current Regulation/Management Part Context

This part belongs to the INA230 series of current sense amplifiers manufactured by Texas Instruments. It is functionally similar to the discontinued INA230AIRGTT, which has been replaced by the RGTR variant. The series is categorized under current sense amplifiers and is designed for integration into embedded monitoring solutions requiring reliable analog-to-digital conversion interfaces.

Current Regulation/Management Replacement Considerations

The INA230AIRGTT is a confirmed substitute part number recommended by the manufacturer as a replacement for legacy designs.
