TS482IDT

Overview

The TS482IDT is a dual Class-AB audio amplifier manufactured by STMicroelectronics, designed for low-voltage portable applications. It operates on a single supply voltage ranging from 2V to 5.5V and is housed in an 8-SOIC surface-mount package. The device delivers 107mW of output power per channel into a 16-ohm load. Key electrical specifications include a gain-bandwidth product of 2.2MHz, a total harmonic distortion plus noise of 0.03%, and a quiescent current of 5.5mA. It features a pop-suppression circuit to eliminate switching transients.

Feature Summary

• Integrated pop-and-click suppression circuitry to prevent audible transients during power-up and power-down sequences.
• Single-supply operation capability with a wide voltage range supporting battery-powered devices.
• High efficiency Class-AB topology optimized for stereo headphone driving applications.

Applications

• Portable MP3 players and digital audio media devices
• Mobile phones and handheld communication terminals
• Personal computers and laptop audio subsystems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and temperature grade. Confirm that the 8-SOIC package dimensions match the target PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level ratings prior to assembly planning.

Selection Notes

Select this component when designing stereo audio paths requiring low supply voltages and minimal external passive components. The integrated pop-suppression feature reduces bill-of-materials complexity compared to discrete solutions. Ensure the thermal performance of the SOIC package meets the ambient operating conditions for the intended enclosure design.

Part Context

This part belongs to the TS482 family of audio amplifiers from STMicroelectronics. The series focuses on providing high-quality audio reproduction in compact form factors suitable for consumer electronics. The IDT suffix typically denotes the specific tape-and-reel or cut-tape packaging variant within the broader product line.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same manufacturer portfolio. Verify that any substitute maintains identical supply voltage ranges and output power capabilities for the target load impedance.
