TS486IQT

Overview

The TS486IQT is a Class-AB stereo audio amplifier manufactured by STMicroelectronics, designed for headphone applications. It operates on a single power supply ranging from 2V to 5.5V and delivers up to 108mW per channel into a 16-ohm load. The device is housed in an 8-DFN (3x3) package with exposed pad for surface mount installation. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated pop-free circuitry to eliminate audible switching noises during power-up and power-down sequences.
• Built-in short-circuit protection mechanisms to safeguard the output stages against fault conditions.
• Dedicated standby mode functionality to significantly reduce current consumption when the device is not in use.

Applications

• Portable digital audio players
• Mobile communication devices
• Personal media players

Procurement Notes

Verify component authenticity through authorized channels as the TS486IQT is marked as obsolete or not recommended for new designs. Confirm RoHS3 compliance status and check for valid replacement alternatives due to potential supply constraints associated with discontinued product lines.

Selection Notes

Select this component for low-voltage stereo audio amplification requiring minimal external components. Ensure the application voltage remains within the 2V to 5.5V range and that the thermal design accommodates the 8-DFN package limitations for continuous operation at elevated temperatures.
