TS487ID

Overview

The TS487ID is a stereo audio power amplifier manufactured by STMicroelectronics, designed for low-voltage portable applications. It delivers 108 mW of output power into an 8-ohm load with a supply voltage range of 2.5 V to 5.5 V. The device operates in Class AB topology and features a built-in standby mode for power conservation. It utilizes an 8-SOIC surface-mount package and supports single-supply operation. Key electrical characteristics include a gain-bandwidth product of 2 MHz and a total harmonic distortion plus noise (THD+N) of 0.15%. The operational temperature range spans from -40°C to +85°C, ensuring reliability in various environments.

Feature Summary

• Stereo headphone amplifier architecture optimized for portable consumer electronics
• Integrated standby mode functionality to minimize quiescent current consumption
• Single-supply operation capability simplifying circuit design requirements
• Class AB output stage providing high fidelity audio reproduction

Applications

• Portable MP3 players and digital audio players
• Mobile phones and handheld communication devices
• Personal media players and portable gaming consoles

Procurement Notes

Verify the specific suffix 'ID' corresponds to the 8-SOIC package variant when sourcing. Confirm RoHS compliance status as regulatory requirements may vary by production batch. Ensure the supplier provides official datasheets matching the TS487ID designation to avoid confusion with similar TS487x family members. Check for obsolete status indicators if long-term availability is required for new designs.

Selection Notes

Select this component for designs requiring stereo amplification with minimal external components. It is suitable for battery-powered systems due to its low supply voltage operation and standby feature. Consider the 8-SOIC package constraints for PCB layout. Verify that the 108 mW output power meets the speaker impedance and volume requirements of the target application.

Part Context

The TS487ID belongs to the TS487 series of audio amplifiers from STMicroelectronics. This series focuses on low-power, high-quality audio solutions for mobile devices. The TS487ID specifically denotes the stereo variant in the SOIC-8 package, distinguishing it from mono or other package options within the same functional family.

Replacement Considerations

Check for direct pin-compatible substitutes within the TS487 family. Verify equivalent performance metrics such as output power and supply voltage range before substitution. Consult manufacturer cross-reference lists for validated alternative part numbers.
