Produktbeskrivning
2 × 100 W class-D power ampli?er
The TDA8920B is a high ef?ciency class-D audio power ampli?er with very low dissipation. The typical output power is 2 × 100W.The ampli?er operates over a wide supply voltage range from +/-12.5V to +/-30V (+/-32V non operating) and consumes a very low quiescent current.
Features
* Zero dead time switching
* Advanced current protection: output current limiting
* Smooth start-up: no pop noise due to DC offset
* High ef?ciency
* Operating supply voltage from +/-12.5V to +/-30V
* Low quiescent current
* Usable as a stereo Single-Ended (SE) ampli?er or as a mono ampli?er in Bridge-Tied Load (BTL)
* Fixed gain of 30dB in Single-Ended (SE) and 36dB in Bridge-Tied Load (BTL)
* High output power
* High supply voltage ripple rejection
* Internal switching frequency can be overruled by an external clock
* Full short-circuit proof across load and to supply lines
* Thermally protected
Applications
* Television sets
* Home-sound sets
* Multimedia systems
* All mains fed audio systems
* Car audio (boosters)
