AS3560-BWLT

Data Sheet AS3560 Class-G Stereo Headphone Amplifier 1 General Description 2 Key Features G-Class amplifier with integrated DCDC buck converter The AS3560 is a Class-G stereo headphone amplifier optimized for usage within portable devices. The Class-G supply rail adaptation is implemented by an integrated DCDC buck converter that takes its input directly from the battery. The continuous adaption of supply rails is done according to the input signal swing and load conditions. This architecture implements significant power savings compared to traditional Class-AB amplifiers. - 2x30mW, 0.02% THD @16Ω - >100dB SNR @1Vrms Charge pump for true ground output without coupling capacitors Direct battery connection with wide supply range: 2.3V to 5.5V Low power consumption optimized for battery operation An I2C control interface is implemented for a 32-step volume control. - 1 mA quiescent current with both channels enabled -
