TS487IDT

Overview

The TS487IDT is a Class AB stereo audio amplifier IC manufactured by STMicroelectronics. It delivers 108 mW per channel into a 16-ohm load with a supply voltage range of 2 V to 5.5 V. The device features a gain-bandwidth product of 1.1 MHz, an input bias current of 200 nA, and an input offset voltage of 1 mV. Operating in an 8-SOIC package, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrated depopulation circuitry for pop-and-click suppression during power transitions
• Built-in short-circuit protection to safeguard the output stages
• Dedicated standby mode for significant power consumption reduction

Applications

• Portable headphone amplification circuits
• Low-power audio playback systems
• Battery-operated consumer electronics

Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm pinout compatibility and thermal characteristics. Ensure the component meets the required industrial temperature grade specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring low-voltage operation and integrated protection features. Consider the 8-SOIC package constraints and verify that the 108 mW output power meets the acoustic requirements of the target speaker or headphone impedance.

Part Context

This part belongs to the TS482/TS487 series of audio amplifiers designed for portable devices. It shares architectural similarities with other members of the family but offers specific performance metrics tailored for stereo headphone driving applications within a compact surface-mount footprint.

Replacement Considerations

Check for direct cross-reference part numbers provided by STMicroelectronics. Verify electrical parameter equivalence and pin-to-pin compatibility if substituting with components from other manufacturers.
