TS486ID

Overview

The TS486ID is a dual-channel Class AB audio amplifier integrated circuit manufactured by STMicroelectronics. Designed for low-voltage applications, it operates within a supply voltage range of 2V to 5.5V. The device delivers a maximum output power of 108mW per channel when driving a 16-ohm load. It is housed in an 8-SOIC surface-mount package with a width of 3.90mm. The component supports stereo headphone outputs and functions reliably across an ambient temperature range of -40°C to +85°C.

Feature Summary

• Integrated pop-suppression circuitry to eliminate audible switching noises during power-up and power-down sequences.
• Built-in short-circuit protection mechanisms safeguard the output stages against direct shorts to ground or the supply rail.
• Dedicated standby mode functionality enables significant reduction in quiescent current consumption for battery-powered systems.

Applications

• Portable digital audio players and MP3 devices
• Mobile telephones and smartphones
• Personal media players

Procurement Notes

Verify the specific suffix 'I' regarding industrial temperature rating (-40°C to +85°C) against design requirements. Confirm package dimensions match the 8-SOIC specification. Note that this product status is marked as discontinued; evaluate long-term availability constraints before finalizing designs.

Selection Notes

Select this component for stereo audio paths requiring minimal external passive components. Ensure the supply voltage remains within the 2V to 5.5V operational window. Verify that the 108mW output capability meets the impedance and sensitivity requirements of the connected headphones or speakers.

Part Context

This part belongs to the TS486 family of audio amplifiers from STMicroelectronics. It serves as a compact solution for consumer electronics where space and power efficiency are critical. The device integrates essential features like pop suppression and standby modes typically found in larger discrete solutions.

Replacement Considerations

Check manufacturer documentation for officially confirmed substitute part numbers. Evaluate pin-to-pin compatibility and electrical parameter equivalence if considering alternative sources.
