Overview
The INA214AIDCKT is a single-channel, bi-directional current shunt monitor from Texas Instruments. It features a zero-drift architecture with an input offset voltage of 1 µV and a gain error of 0.02%. The device operates on a single supply voltage ranging from 2.7 V to 26 V, consuming a maximum supply current of 100 µA. It provides a fixed voltage gain of 100 V/V and supports high-side or low-side measurements with a common-mode voltage range of -0.3 V to 26 V. The component is housed in a SC-70-6 package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Zero-drift architecture ensures low offset voltage for accurate sensing of small shunt voltages
- Bi-directional capability allows measurement of current flow in both directions
- Supports high-side and low-side current monitoring configurations
- Wide common-mode voltage range enables operation independent of supply voltage
Applications
- Battery management systems
- Overcurrent protection circuits
- Load switch control
- Power delivery monitoring
Procurement Notes
Verify the specific suffix 'CKT' indicates Cut Tape packaging when ordering. Confirm the 'A' grade designation matches required offset voltage specifications. Ensure the SC-70-6 footprint aligns with PCB design constraints. Check moisture sensitivity levels if reflow soldering is planned. Validate that the 100 V/V gain meets system signal requirements.
Selection Notes
Select this part for applications requiring high precision in low-voltage drop sensing. The zero-drift technology minimizes calibration needs compared to standard amplifiers. Consider the 100 µA supply current for battery-powered designs. The wide common-mode range simplifies high-side placement. Verify thermal performance at maximum operating temperatures.
Part Context
The INA214 belongs to the INA21x series of current shunt monitors designed for precision measurement. This family utilizes chopper-stabilized amplifiers to achieve near-zero drift characteristics. The device integrates a fixed gain amplifier to simplify external component selection. It is intended for industrial and automotive environments requiring reliable current monitoring.
Replacement Considerations
INA214BIDCKT offers similar functionality with potentially different initial offset voltage grades. INA215AIDCKT provides a different fixed gain of 75 V/V while maintaining comparable electrical characteristics.
