INA214AIRSWT

Overview

The INA214AIRSWT is a unidirectional current shunt monitor manufactured by Texas Instruments, housed in a UQFN-10 package. It features a fixed gain of 100 V/V and operates within a supply voltage range of 2.7 V to 26 V. Key electrical specifications include a maximum input offset voltage of 1 uV, an input bias current of 28 uA, and a gain error of 0.02%. The device supports a common-mode voltage up to 12 V and offers a common-mode rejection ratio of 140 dB. It functions with a quiescent current of 100 uA and maintains performance across an operating temperature range from -40 C to +125 C.

Feature Summary

• Provides high precision measurement capabilities through ultra-low input offset voltage and minimal gain error characteristics.
• Supports bidirectional current sensing functionality for versatile monitoring applications.
• Enables operation in low-power systems via reduced quiescent current consumption.

Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control

Procurement Notes

Verify the specific suffix 'AW' against the official datasheet to confirm the exact temperature grade and packaging configuration intended for your design. Confirm that the component status aligns with long-term availability requirements, as lifecycle changes may impact future production runs. Ensure compatibility with your assembly processes regarding the UQFN-10 package type.

Selection Notes

Select this component when designing circuits requiring precise current monitoring with low power consumption. The fixed 100 V/V gain simplifies signal conditioning for standard shunt resistors. Consider the 12 V common-mode limit when selecting shunt placement relative to the system ground potential. Evaluate thermal dissipation needs given the small form factor and operating temperature range.

Part Context

This part belongs to the INA214 series of current sense amplifiers designed for high-accuracy applications. It shares architectural similarities with other devices in the family but is distinguished by its specific gain setting and package variant. The series targets industrial and automotive environments where reliability and precision are critical for system safety and efficiency.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified alternatives. Ensure any substitute matches the UQFN-10 footprint and pinout to maintain board compatibility without redesigning the layout.
