INA283AIDGKT

Current Regulation/Management Overview

The INA283AIDGKT is a bidirectional current sense amplifier manufactured by Texas Instruments, designed for high-voltage applications with a common-mode voltage range of -14 V to 80 V. It features a fixed gain of 25 V/V and operates on a single supply voltage between 2.7 V and 18 V. The device draws a maximum quiescent current of 600 µA and maintains an accuracy of 1.4% over the specified temperature range. It supports both high-side and low-side sensing configurations and is housed in an 8-pin VSSOP package suitable for surface-mount installation.

Current Regulation/Management Feature Summary

• Supports bidirectional current sensing across a wide common-mode voltage range from -14 V to 80 V
• Provides a fixed gain of 25 V/V for simplified system design
• Enables operation in both high-side and low-side circuit topologies

Current Regulation/Management Applications

• Industrial motor control systems
• Power supply monitoring circuits
• Battery management systems

Current Regulation/Management Procurement Notes

Verify that the suffix 'KT' corresponds to the tape-and-reel packaging format as specified in the official datasheet. Confirm the device grade matches the required operational temperature range of -40°C to +125°C. Ensure compatibility with the target PCB footprint for the VSSOP-8 package. Cross-reference the manufacturer part number against the latest product change notifications to confirm material and manufacturing consistency.

Current Regulation/Management Selection Notes

Select this component when bidirectional current measurement is required within a high common-mode voltage environment up to 80 V. The fixed 25 V/V gain simplifies signal conditioning compared to programmable alternatives. Consider the 600 µA quiescent current for power-sensitive designs. Verify that the input common-mode range covers the negative voltages present in the application, distinguishing it from unidirectional sensors.

Current Regulation/Management Part Context

This part belongs to the INA283 family of current sense amplifiers. It shares the core functional architecture with the INA283AIDGKR variant, differing primarily in the reel-based packaging configuration indicated by the 'KT' suffix. Both variants offer identical electrical performance characteristics and pinout definitions for interchangeable use in hardware designs.
