INA282AIDGKR

Current Regulation/Management Overview

The INA282AIDGKR is a bidirectional current shunt monitor manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It operates with a supply voltage range of 2.7 V to 18 V and supports common-mode input voltages from -14 V to 80 V. The device features a fixed gain of 50 V/V and offers high accuracy with a maximum error of 1.4%. It draws a typical operating supply current of 600 µA and functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Supports bidirectional current sensing for both high-side and low-side configurations.
• Utilizes zero-drift architecture to maintain high precision over temperature variations.
• Provides rail-to-rail output capability compatible with single-supply systems.

Current Regulation/Management Applications

• Battery management systems
• Industrial process control
• Power supply monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix 'KR' indicates tape-and-reel packaging when sourcing. Confirm the A-grade accuracy specification aligns with design requirements. Ensure the VSSOP-8 footprint matches the target PCB layout. Check for RoHS compliance status relevant to the manufacturing region.

Current Regulation/Management Selection Notes

Select this component for applications requiring precise bidirectional current measurement in harsh environments. The wide common-mode voltage range allows flexibility in system topology. Consider the low quiescent current for battery-powered designs. Verify thermal performance within the specified operating temperature limits.

Current Regulation/Management Part Context

This part belongs to the INA282 family of zero-drift current shunt monitors. It complements other variants like the INA282AIDGKT, differing primarily in packaging format. The series is designed for high-accuracy industrial and automotive applications where drift compensation is critical.

Current Regulation/Management Replacement Considerations

The INA282AIDGKT is a verified substitute offering identical electrical characteristics in a VSSOP-8 package. Both parts share the same pinout and functionality, allowing for direct replacement if reel availability differs.
