austriamicrosystems has announced the AS3560 and AS3561 stereo headphone amplifiers which continuously adjust the supply rails in response to the input signal, in an effort to reduce power consumption as compared to traditional Class AB amplifiers. The AS3560 is a Class G amplifier while the AS3561 extends the power savings even more with a Class H topology. Both 30 mW devices use differential line inputs to minimise the effects of ground noise and EMI susceptibility, and also feature low quiescent current of 1 mA with both channels enabled. Shutdown current is less than 5 μA. Audio figures include >100 dB SNR @ 1 Vrms and THD of 0,02% at 16 Ω. The integrated charge pump generates a symmetric negative supply for true ground output signal levels. An I²C bus allows volume control with 32 gain steps as well as independent channel control.
