DS2105 Ver1.0 June 2009 5-W Stereo Class-D Audio Amplifier with 64-Step DC Volume Control
DESCRIPTION
The EUA2105 is a high efficiency, 2 channel bridged-tied load (BTL), class-D audio power amplifier. Operating from a 12V power supply, EUA2105 is capable of delivering 5W/ channel of continuous output power to a 8 Ω load with 1% THD+N. The EUA2105 features a differential input architecture offering improved noise immunity over a single-ended (SE) input amplif ier. Stereo speaker volume is controlled with a dc voltage applied to the volume control terminal offering a range of gain from -68dB to32 dB. The EUA2105 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2105 is available in thermally efficient 28-pin TSSOP package.
