INA214AIDCKR-S

Overview

The INA214AIDCKR-S is a bidirectional, zero-drift current-shunt monitor manufactured by Texas Instruments. It features a fixed gain of 100 V/V and operates on a single supply voltage ranging from 2.7 V to 26 V. The device offers a -3 dB bandwidth of 30 kHz and a common-mode rejection ratio (CMRR) of 140 dB. Input bias current is specified at 28 uA, with an input offset voltage of 1 uV. It consumes 100 uA of operating supply current and functions within a temperature range of -40°C to +125°C. The component is housed in a SC-70-6 package.

Feature Summary

• Bidirectional measurement capability for high-side and low-side current sensing applications
• Zero-drift architecture ensures minimal input offset voltage drift over temperature variations
• High common-mode rejection ratio supports accurate measurements in noisy environments

Applications

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

Procurement Notes

Verify the specific suffix 'S' against official Texas Instruments documentation to confirm package details and availability status. Ensure compatibility with SC-70-6 footprint requirements during PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when precise bidirectional current monitoring is required in space-constrained designs. The zero-drift technology minimizes calibration needs compared to standard amplifiers. Consider the 30 kHz bandwidth for applications requiring moderate speed without excessive power consumption. Verify that the 2.7 V minimum supply voltage aligns with the system's power rails.

Part Context

This device belongs to the INA214 family of current sense amplifiers. It shares architectural similarities with other zero-drift monitors but is distinguished by its specific gain and packaging configuration. The series is designed for applications demanding high accuracy and stability in industrial and automotive environments.

Replacement Considerations

Official substitutes include the INA214BIDCKT and INA214AIRSWT. Verify pinout compatibility and gain specifications before substitution. Ensure thermal performance and package dimensions match the existing design constraints.
