General description
The TDA8950 is a high efficiency class-D audio power amplifier. The typical output power
is 2 ´ 150 W with a speaker load impedance of 4 W.
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-Tied
Load (BTL) amplifier
 High output power at typical applications:
  SE 2 ´ 150 W, RL = 4 W (VP = ±37 V)
  SE 2 ´ 170 W, RL = 4 W (VP = ±39 V)
  SE 2 ´ 100 W, RL = 6 W (VP = ±37 V)
  BTL 1 ´ 300 W, RL = 8 W (VP = ±37 V)
 Low 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 BTL
 Full short-circuit proof across load
