TDA8953
Overview
The TDA8953 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 Ω load in a stereo Single-Ended (SE) application, or 1 × 420 W into an 8 Ω load in a mono Bridge-Tied Load (BTL) application.
- High output power in typical applications:
- SE 2 × 210 W, RL = 4 Ω (VDD = 41 V; VSS = -41 V)
- SE 2 × 235 W, RL = 3 Ω (VDD = 39 V; VSS = -39 V)
- SE 2 × 150 W, RL = 6 Ω (VDD = 41 V; VSS = -41 V)
- BTL 1 × 420 W, RL = 8 Ω (VDD = 41 V; VSS = -41 V)
- Symmetrical operating supply voltage range from ±12.5 V to ±42.5 V
- Stereo full differential inputs, can be used as stereo SE or mono BTL amplifier
- Low noise
- Smooth pop noise-free start-up and switch off
- Fixed frequency internal or external clock
