Overview
The TS486-1IST is a dual audio power amplifier manufactured by STMicroelectronics, designed for single-ended operation. It delivers approximately 107 mW of output power into a 32 Ohm load with a total harmonic distortion plus noise of 0.03%. The device operates on a single supply voltage ranging from 2 V to 5.5 V and draws a typical quiescent current of 5.5 mA. It features a gain-bandwidth product of 2.2 MHz and an input bias current of 500 nA. The component is housed in an 8-pin TSSOP package and supports surface mount installation.
Feature Summary
- Dual-channel stereo configuration capable of driving 16 or 32 Ohm loads
- Class-AB topology for efficient audio amplification
- Single-supply operation suitable for portable applications
Applications
- Stereo headset driving
- Portable audio devices
- Headphone amplifiers
Procurement Notes
Verify the specific suffix 'IST' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status through the latest regulatory documentation. Ensure the source provides valid traceability for this obsolete part number before finalizing procurement decisions.
Selection Notes
Select this component when a dual-channel Class-AB amplifier is required for low-power stereo applications. It is suitable for designs needing single-supply operation with moderate output power. Consider the TSSOP-8 package constraints and thermal dissipation requirements relative to the target enclosure design.
Part Context
This component belongs to the TS486/TS487 series of audio power amplifiers. The TS486 variant specifically offers dual-channel stereo capability, distinguishing it from mono variants like the TS487. It is engineered for consumer electronics requiring compact solutions for headphone or small speaker drivers.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference availability directly with the manufacturer or authorized distributors.
