HLF TEA2025 – AB-Class Dual Channel Audio Power Amplifier (DIP16) | Stereo 2.3W ×2 @12V | BTL 4.7W @9V | 3V–12V, 0°C to +70°C | Through-Hole Package

The HLF TEA2025 (DIP16) is a dual-channel AB-class audio power amplifier designed for low-distortion and low-noise operation in compact audio systems. It can operate in stereo mode, delivering up to 2.3W ×2 output at 12V (8Ω load), or in BTL (Bridge-Tied Load) mode providing up to 4.7W output at 9V (8Ω load).

Operating from a wide supply range of 3V to 12V, the TEA2025 offers low quiescent current (40 mA) and excellent total harmonic distortion (0.30%), making it ideal for portable, consumer, and multimedia audio applications. Its built-in thermal shutdown and short-circuit protection ensure reliable long-term performance.
