INA2180A4IDGKT

Overview

The INA2180A4IDGKT 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. It is housed in an 8-VSSOP package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel architecture for simultaneous bidirectional current monitoring
• High common-mode voltage tolerance up to 12 V
• Fixed internal gain of 200 V/V for simplified circuit design
• Wide operating temperature range suitable for industrial environments

Applications

• Battery management systems requiring precise current measurement
• Industrial process control loops with low-voltage power supplies
• Overcurrent protection circuits in portable electronic devices
• Power distribution units in embedded systems

Procurement Notes

Verify the specific suffix IDGKT corresponds to the 8-VSSOP tape-and-reel packaging configuration. Confirm the A4 grade designation matches required accuracy specifications for your application. Ensure compatibility with standard surface-mount reflow processes given the small outline package dimensions. Check for any regional compliance certifications if deploying in regulated markets.

Selection Notes

Select this component when dual-channel sensing is required within a 5.5 V system limit. The 12 V common-mode range allows flexibility in high-side placement relative to ground potential. Consider the 200 V/V gain factor against expected signal levels to avoid saturation. Evaluate the 350 kHz bandwidth against noise requirements and switching frequencies in the target power stage.

Part Context

This part belongs to the INA2180 family of current sense amplifiers designed for low-voltage, space-constrained applications. It complements other variants like the INA2181 which may offer different pinouts or gain options. The series targets cost-sensitive designs where precision and compact footprint are prioritized over ultra-high voltage capabilities.
