| 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 load with 1% THD+N. The EUA2105 features a differential input architecture offering improved noise immunity over a single-ended (SE) input amplifier. 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. EUA2105 FEATURES Wide Supply Voltage: 8V to 15V Unique Modulation Scheme Reduces EMI Emission 5W/ch into an 8 Load From 12V Supply Efficient, Class-D Operation Eliminates Heatsinks 64-Step DC Volume Control From -68dB to 32dB Thermal and Short-Circuit Protection Integrated Click and Pop Suppression 28-pin TSSOP Package with Thermal Pad RoHS compliant and 100% lead(Pb)-free APPLICATIONS LCD Monitors/TVs All-in-One PCs Typical Application Circuit Figure1.
