TDA8954TH 

NXP Semiconductors  HSOP24 2×210 W class D Integrated circuit (IC) Linear - amplifier - audio


TDA8954TH A single IC with low power consumption. It is designed to transmit power up to 2×210 W to Stereo single-ended (SE) applications in 4Ω loads, or in Single bridge connection load (BTL) application.
TDA8954TH combines the benefits of class D efficiency (≈93% at 4Ω load) and audiophiles.

Sound quality is comparable to Class AB amplification.

The amplifier operates over a wide supply voltage range from ± 12.5V to ± 42.5V.
Low static current consumption.

TDA8954TH Features:

High output power in typical applications:

SE 2×210 W,RL=4Ω(VDD=41 V;VSS=-41 V)

SE 2×235 W,RL=3Ω(VDD=39 V;VSS=-39 V)

SE 2×150 W,RL=6Ω(VDD=41 V;VSS=-41 V)

BTL 1×420 W,RL=8Ω(VDD=41 V;VSS=-41 V)

Symmetrical operating supply voltage range from±12.5V to±42.5V
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
