TDA8950
Overview
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 Ω.
- Features I Pin compatible with TDA8920B for both HSOP24 and DBS23P packages I Symmetrical operating supply voltage range from ±12.5 V to ±40 V I Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier I High output power in typical applications: N SE 2 × 150 W, RL = 4 Ω (VP = ±37 V) N SE 2 × 170 W, RL = 4 Ω (VP = ±39 V) N SE 2 × 100 W, RL = 6 Ω (VP = ±37 V) N BTL 1 × 300 W, RL = 8 Ω (VP = ±37 V) I Low noise I Smooth pop noise-free start-up and switch off I Zero dead time switching I Fixed frequency I Internal or external clock I High efficiency I Low quiescent current I Advanced protection strategy: voltage protection and output current limiting I Thermal FoldBack (TFB) I Fixed gain of 30 dB in SE and 36 dB in BTL applications I Fully short-circuit proof across load I BD modulation in BTL configuration
