INA208AIDG4

Current Regulation/Management Overview

The INA208AIDG4 is a high-side current-shunt monitor manufactured by Texas Instruments in a 14-pin SOIC package. It features an integrated voltage reference, dual comparators, and a fixed gain of 20 V/V. The device supports input voltages from -16V to 80V and provides a current output of 1mA. It operates within a temperature range of -40°C to 85°C and offers ±3.5% accuracy.

Current Regulation/Management Feature Summary

• Integrates dual comparators and a precision voltage reference for simplified system design
• Supports high-side current sensing with wide common-mode voltage range
• Provides fixed gain amplification for direct shunt voltage monitoring

Current Regulation/Management Applications

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

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free and RoHS compliance as per Texas Instruments documentation. Confirm the 14-SOIC package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with your design constraints.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required with integrated signal conditioning. The fixed 20 V/V gain suits applications where precise shunt voltage amplification is needed without external resistors. Consider the dual comparators for overcurrent protection logic. Verify that the 1mA output interface matches your downstream ADC or microcontroller input requirements.

Current Regulation/Management Part Context

This part belongs to the INA20x family of current-shunt monitors. It differs from lower-gain variants by providing a fixed 20 V/V amplification factor. The integration of comparators distinguishes it from basic amplifier-only models like the INA206. It serves as a complete solution for monitoring and protection in power distribution networks.

Current Regulation/Management Replacement Considerations

Check for pin-compatible alternatives within the INA20x series if different gain options are needed. Verify that substitute parts support the same 80V common-mode voltage range. Ensure replacement components maintain the dual comparator functionality if protection logic is critical to the application design.
