Brief Introduction

TDA8920CTH

<p>The TDA8920C is a high-efficiency class-D audio power amplifier. The typical output</p><p>power is 2 × 110 W with a speaker load impedance of 4 Ω.</p><p>The TDA8920C is available in both HSOP24 and DBS23P power packages. The amplifier</p><p>operates over a wide supply voltage range from ±12.5 V to ±32.5 V and features low</p><p>quiescent current consumption.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;■ Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages</p><p>■ Symmetrical operating supply voltage range from ±12.5 V to ±32.5 V</p><p>■ Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono</p><p>Bridge-Tied Load (BTL) amplifier</p><p>■ High output power in typical applications:</p><p>◆ SE 2 × 110 W, RL = 4 Ω (VP = ±30 V)</p><p>◆ SE 2 × 125 W, RL = 4 Ω (VP = ±32 V)</p><p>◆ SE 2 × 120 W, RL = 3 Ω (VP = ±29 V)</p><p>◆ BTL 1 × 220 W, RL = 8 Ω (VP = ±30 V)</p><p>■ Low noise</p><p>■ Smooth pop noise-free start-up and switch off</p><p>■ Zero dead time switching</p><p>■ Fixed frequency</p><p>■ Internal or external clock</p><p>■ High efficiency</p><p>■ Low quiescent current</p><p>■ Advanced protection strategy: voltage protection and output current limiting</p><p>■ Thermal FoldBack (TFB)</p><p>■ Fixed gain of 30 dB in SE and 36 dB in BTL applications</p><p>■ Fully short-circuit proof across load</p><p>■ BD modulation in BTL configuration</p>
