INA2180A2IDGKT

Overview

The INA2180A2IDGKT is a dual-channel current-sense amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a common-mode voltage up to 12 V. The device features a fixed gain of 200 V/V, a bandwidth of 350 kHz, and an input offset voltage of 100 µV. Packaged in an 8-VSSOP format, it functions across a temperature range of -40°C to +125°C with a typical supply current of 500 µA.

Feature Summary

• Dual-channel architecture for simultaneous multi-rail monitoring
• High common-mode voltage tolerance up to 12 V
• Fixed high gain configuration for simplified circuit design
• Rail-to-rail output capability

Applications

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

Procurement Notes

Verify the specific suffix 'A2' against the official datasheet to confirm the fixed gain value, as variations exist within the family. Ensure the 'DGKT' package designation matches the required VSSOP-8 reel specifications. Cross-reference the manufacturer part number directly with the source document to avoid confusion with similar current-sense amplifiers.

Selection Notes

Select this component when dual-channel sensing is required within a single package footprint. The 12 V common-mode range accommodates higher voltage rails compared to standard 5 V parts. Verify that the 200 V/V gain meets the system's resolution requirements without saturating the output under maximum load conditions.

Part Context

This part belongs to the INA2180 series of precision current-sense amplifiers. It shares the core topology with other variants like the INA2180A1 and INA2180A4, differing primarily in gain settings and channel configurations. The series is designed for low-cost, high-accuracy current monitoring in space-constrained applications.

Replacement Considerations

Direct substitutes include other members of the INA2180 family such as the INA2180A1IDGKT or INA2180A4IDGKT, provided the gain difference is acceptable. For pin-compatible alternatives with different gains, verify the external resistor network requirements.
