TDA8950J/N1,112 Datasheet PDF - NXP

●Overview

●The TDA8950 is a high-efficiency Class D audio power amplifier. The typical output power is 2 x 150 W with a speaker load impedance of 4 Ω.

●The TDA8950 is available in both HSOP24 and DBS23P power packages. The amplifier operates over a wide supply voltage range from +-12.5 V to +-40 V and features low quiescent current consumption.

●## Features

● Pin compatible with TDA8920B for both HSOP24 and DBS23P packages

● Symmetrical operating supply voltage range from +-12.5 V to +-40 V

● Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier

● High output power in typical applications:

● SE 2 x 150 W, RL = 4 Ω (VP = +-37 V)

● SE 2 x 170 W, RL = 4 Ω (VP = +-39 V)

● SE 2 x 100 W, RL = 6 Ω (VP = +-37 V)

● BTL 1 x 300 W, RL = 8 Ω (VP = +-37 V)

● Low noise

● Smooth pop noise-free start-up and switch off

● Zero dead time switching

● Fixed frequency

● Internal or external clock

● High efficiency

● Low quiescent current

● Advanced protection strategy: voltage protection and output current limiting

● Thermal FoldBack (TFB)

● Fixed gain of 30 dB in SE and 36 dB in BTL applications
