INA216A1YFFR

Current Regulation/Management Overview

The INA216A1YFFR is a small-size, low-power, unidirectional current shunt monitor manufactured by Texas Instruments. It features zero-drift architecture for high precision and operates with input voltages ranging from 1.8V to 5.5V. The device offers a bandwidth of 20kHz and utilizes a DSBGA-4 package measuring 0.8x0.8mm. It supports surface mount installation and functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Zero-drift technology ensures high accuracy without external calibration
• Ultra-small footprint suitable for space-constrained designs
• Low quiescent current consumption for power efficiency
• High common-mode voltage range compatibility

Current Regulation/Management Applications

• Portable battery-powered equipment monitoring
• Industrial process control current sensing
• Overcurrent protection circuits
• Power management systems in consumer electronics

Current Regulation/Management Procurement Notes

Verify the specific suffix YFFR corresponds to the DSBGA-4 package and tape-and-reel quantity when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to procurement. Ensure the selected variant matches the required accuracy grade A1 for the intended application specifications.

Current Regulation/Management Selection Notes

Select this component for applications requiring precise DC current measurement in compact form factors. The zero-drift characteristic minimizes offset errors over temperature variations. Consider the 20kHz bandwidth limitation for high-frequency switching applications. Evaluate the unidirectional nature against bidirectional sensing requirements.

Current Regulation/Management Part Context

This part belongs to the INA216 family of current shunt monitors designed for low-power, high-precision sensing. It complements other variants like INA216A2 and INA216A3 which may offer different packages or accuracy grades. The series focuses on eliminating chopper artifacts common in traditional zero-drift amplifiers.

Current Regulation/Management Replacement Considerations

Direct substitutes include INA216A2YFFR and INA216A3YFFR from the same manufacturer. Verify pinout compatibility and accuracy class differences before substitution. Cross-reference datasheets for any changes in common-mode voltage ranges or thermal performance characteristics.
