1 / 39 page 1. 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 Ω. 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. 2. Features I Pin compatible with TDA8920B for both HSOP24 and DBS23P packages I Symmetrical high operating supply voltage range from ±12.5 V to ±40 V I Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier I High output power at 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 in BTL due to BD-modulation I Smooth pop noise-free start-up and switch down I Zero dead time Pulse Width Modulation (PWM) output switching I Fixed frequency I Internal or external clock switching frequency I High efficiency I Low quiescent current I Advanced protection strategy: voltage protection and output current limiting I Thermal foldback I Fixed gain of 30 dB in SE and 36 dB in BTL I Full short-circuit proof across load 3. Applications I DVD I Mini and micro receiver I Home Theater In A Box (HTIAB) system I High power speaker system TDA8950 2 × 150 W class-D power amplifier Rev. 01 — 9 September 2008 Preliminary data sheet |
