“The TDA8950 is a high efficiency class-D audio power amplifier. The typical output poweris 2× 150 W with a speaker load impedance of 4Ω.The

TDA8950 is available in the HSOP24 power package and DBS23P power package. The amplifier operates over a wide supply voltage range from ±12.5 V to ±40 V and consumes a low quiescent current.

Features:

Pin compatible with TDA8920B for both HSOP24 and DBS23P packages
Symmetrical high operating supply voltage range from ±12.5 V to± 40 V
Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-TiedLoad (BTL) amplifier
High output power at typical applications:uSE 2×150 W, RL=4Ω (VP =±37 V)uSE 2×170 W, RL=4Ω (VP =±39 V)uSE 2×100 W, RL= 6Ω (VP =±37 V)uBTL 1×300 W, RL=8Ω (VP =±37 V)nLow noise in BTL due to BD-modulation
Smooth pop noise-free start-up and switch down
Zero dead time Pulse Width Modulation (PWM) output switching
Fixed frequency
Internal or external clock switching frequency
High efficiency
Low quiescent current
Advanced protection strategy: voltage protection and output current limiting Thermal foldback
Fixed gain of 30 dB in SE and 36 dB in BTLnFull short-circuit proof across load
