High-performance class-G stereo headphone amplifier

The A22H165 is a class-G stereo headphone driver dedicated to high-performance audio, high power efficiency and space-constrained applications. It is based on the core technology of a low power dissipation amplifier combined with a high efficiency step-down DC-DC converter for supplying this amplifi Power supply range: 2.3 V to 4.8 V\n0.6 mA/channel quiescent current\n2.1 mA current consumption with 100 μW/channel (10 dB crest factor)\n0.006% typical THD+N at 1 kHz\n100 dB typical PSRR at 217 Hz\n100 dB of SNR A-weighted at G = 0 dB\nZero \"pop and click\"\nGain settings: 0 dB and 6 dB\nInt;
