Overview
The TS486IST is a Class-AB audio power amplifier manufactured by STMicroelectronics, designed for stereo headphone applications. It operates within a supply voltage range of 2V to 5.5V and delivers up to 108mW per channel into a 16-ohm load. The device is housed in an 8-SOIC surface-mount package with a width of 3.90mm. It features integrated pop-and-click suppression, short-circuit protection, and standby functionality. The operational temperature range spans from -40°C to +85°C.
Feature Summary
- Integrated pop-and-click suppression circuitry to minimize audible noise during power transitions
- Built-in short-circuit protection for output channels to enhance reliability under fault conditions
- Dedicated standby mode for effective power management in battery-operated portable devices
Applications
- Stereo headphone amplification in mobile phones and handheld devices
- Audio output stages in portable media players
- Low-power audio systems in personal digital assistants
Procurement Notes
Verify the specific suffix 'IST' against official STMicroelectronics documentation to confirm package type and tape/reel specifications. Confirm current availability status as product lifecycle data may indicate obsolescence or end-of-life status. Ensure compatibility with required operating temperature ranges and RoHS compliance standards before integration.
Selection Notes
Select this component for designs requiring a compact stereo amplifier solution with low quiescent current. The 8-SOIC package suits space-constrained printed circuit board layouts. Verify that the 16-ohm load impedance matches the target speaker or headphone specifications to achieve optimal power delivery without exceeding thermal limits.
Part Context
The TS486 series belongs to STMicroelectronics' portfolio of ultra-low-power audio amplifiers. This family targets portable consumer electronics where battery life and physical size are critical constraints. The TS486IST variant specifically denotes the industrial temperature grade and surface-mount packaging configuration within this product line.
Replacement Considerations
Check for direct pin-compatible substitutes within the TS486 family or newer generations such as the TS4861. Verify that any replacement maintains identical supply voltage ranges, output power capabilities, and package dimensions to ensure seamless board-level integration.
