Product Description

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 x 210 W into a 4 Ω load in a stereo Single-Ended (SE) application, or 1 x 420 W into an 8 Ω load in a mono Bridge-Tied Load (BTL) application.
It combines the benefits of Class D efficiency (≈93 % into a 4 Ω load) with audiophile sound quality comparable to that associated with Class AB amplification.
The amplifier operates over a wide supply voltage range from ±12.5 V to ±42.5 V and features low quiescent current consumption.

## Features
* High output power in typical applications:
* SE 2 x 210 W, RL = 4 Ω (VDD = 41 V; VSS = -41 V)
* SE 2 x 235 W, RL = 3 Ω (VDD = 39 V; VSS = -39 V)
* SE 2 x 150 W, RL = 6 Ω (VDD = 41 V; VSS = -41 V)
* BTL 1 x 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
* High efficiency ≈93 %
* Zero dead time switching
* Low quiescent current
* Advanced protection strategy: voltage protection and output current limiting
* Thermal FoldBack (TFB) with disable functionality
* Fixed gain of 30 dB in SE and 36 dB in BTL applications
* Fully short-circuit proof across load
* BD modulation in BTL configuration
* Clock protection
## Target Applications
* DVD
* Mini and micro receiver
* Subwoofers
* Home Theater In A Box (HTIAB) system
* High-power speaker system
* Public Address (PA) system
