Overview
The TS482IST is a dual audio power amplifier from STMicroelectronics, designed to drive 16 or 32-ohm stereo headsets at low voltages. It operates within a supply voltage range of 2V to 5.5V and delivers up to 107 mW per channel into 16-ohm loads with 0.1% THD+N at 5V. The device features Class-AB output topology, single-ended input and output configurations, and a gain-bandwidth product of 2.2 MHz. It consumes 5.5 mA of operating current and supports an input bias current of 500 nA. Packaged in TSSOP-8 for surface-mount installation, it functions between -40°C and +85°C.
Feature Summary
- Rail-to-rail input and output capability ensures maximum dynamic range.
- Unity-gain stable architecture allows flexible external gain configuration via resistors.
- Integrated switch ON/OFF click reduction circuitry minimizes audible artifacts during power transitions.
Applications
- Stereo headset driving
- Portable audio devices
- Low-voltage consumer electronics
Procurement Notes
Verify the specific suffix 'IST' corresponds to the TSSOP-8 package and reel/cut tape availability as listed by distributors. Confirm RoHS compliance status through official documentation before integration. Ensure the ordering part number matches the required thermal and mechanical specifications for the target PCB layout.
Selection Notes
Select this component for applications requiring high signal-to-noise ratio (110dB) and high power supply rejection ratio (85dB). It is suitable for designs needing rail-to-rail performance and low quiescent current. Consider the 2V minimum supply voltage constraint when designing battery-powered systems.
Part Context
The TS482IST belongs to the TS482 series of audio amplifiers. This family includes variants available in SO-8, MiniSO-8, and DFN8 packages. The series is characterized by its ability to deliver high power efficiency in small form factors, targeting portable multimedia applications.
Replacement Considerations
Check for other TS482 series variants with different package options if physical footprint constraints change. Verify pinout compatibility before substituting with similar dual-channel headphone amplifiers from other manufacturers.
