The TDA8954 is a stereo or mono high-efficiency Class D audio power amplifier in a single IC featuring low power dissipation. It is designed to deliver up to 2 × 210 W into a 4 R load in a stereo Single-Ended (SE) application, or 1 × 420 W into an 8 R load in a mono Bridge-Tied Load (BTL) application.
