Product Description

Overview
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 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.
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.
The TDA8954 is supplied with two diagnostic pins for monitoring the status of Thermal Fold Back (TFB), Over Current Protection (OCP) and other protection circuits.

## Features
* 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
* 2-pin diagnostics for protection circuits
* 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
