TEA2025D013TR

Overview

The TEA2025D013TR is a dual or bridge power audio amplifier IC manufactured by STMicroelectronics, housed in an SO20 (12+4+4) surface-mount package. It operates on a supply voltage range of 3V to 15V. In stereo mode at 9V with a 4Ω load, it delivers up to 2.3W per channel. In bridge mode at 9V with an 8Ω load, it provides up to 4.7W output power. The device features a maximum gain of 45dB adjustable via external resistors and includes built-in thermal protection.

Feature Summary

• Supports both dual stereo and bridge connection modes for flexible system design
• Integrates internal soft clipping and thermal protection circuits
• Features very low switch-on/off noise without requiring external components
• Requires few external components due to integrated DC decoupling and feedback networks

Applications

• Portable radio cassette players
• Dual channel audio amplification systems
• Bridge-connected high-power audio applications

Procurement Notes

Verify the specific ordering suffix 'D013TR' corresponds to the SO16 tape and reel configuration as listed in the datasheet order codes, distinct from the standard SO20 version. Confirm that the component status is obsolete and identify suitable replacement strategies if current production availability is required for new designs.

Selection Notes

Select this component when a dual-channel or bridgeable AB-class amplifier is needed within a 3V to 15V supply range. It is suitable for designs prioritizing minimal external component count and integrated protection features like thermal shutdown and pop-noise suppression over ultra-high efficiency class-D performance.

Part Context

This part belongs to the TEA2025 family of monolithic integrated circuits designed for portable audio applications. The D013TR variant specifically denotes the surface-mount packaging option, differing from the PowerDIP16 through-hole version (TEA2025B). It shares core electrical characteristics with the broader series while offering PCB layout advantages.

Replacement Considerations

The datasheet lists the TEA2025B (PowerDIP) and TEA2025D (SO20) as related parts. No direct pin-compatible active substitutes are confirmed in the provided documentation.
