TS3A227EYFFR

Overview

The TS3A227EYFFR is a Texas Instruments audio detection switch housed in a 16-DSBGA package. It operates on a single supply voltage ranging from 2.5 V to 4.5 V and supports an operating temperature range of -40°C to +85°C. The device integrates I2C interface functionality for control and status monitoring. Designed for surface mount installation, it serves as a specialized component for consumer audio applications requiring automated accessory detection.

Feature Summary

• Integrated I2C interface for digital control and status reporting
• Single-supply operation between 2.5 V and 4.5 V
• Compact 16-DSBGA (1.56x1.56 mm) surface-mount package

Applications

• Consumer audio devices
• Headset jack detection circuits
• Accessory identification systems

Procurement Notes

Verify the specific datasheet revision and electrical characteristics against the official Texas Instruments documentation before integration. Confirm that the 16-DSBGA footprint matches the design layout. Ensure the I2C address configuration aligns with the system bus requirements. Check for any specific handling or storage conditions outlined in the manufacturer's guidelines.

Selection Notes

Select this component when an I2C-controlled audio detection solution is required within a 2.5 V to 4.5 V supply range. The 16-DSBGA package is suitable for space-constrained designs. Compare performance metrics such as leakage current and switching speed against alternative switches if precise signal integrity is critical for the specific audio path application.

Part Context

This part belongs to the Texas Instruments audio switch family, specifically engineered for detecting connected accessories like headsets or microphones. The YFFR suffix indicates the 16-DSBGA package type and reel packaging format. It replaces older discrete detection circuits by integrating analog switching and digital communication into a single small form factor.

Replacement Considerations

Direct replacements must support I2C control and operate within the 2.5 V to 4.5 V range. Verify pin compatibility for the 16-DSBGA package. Consider alternatives like the TS3A22766 if additional channels are needed, ensuring the substitute maintains similar detection logic and thermal performance.
