iQube V5
產品介紹

Lightweight, portable Headphone amplifier
High efficiency (90-95%) Class D amplifier
Built in USB receiver and separate DAC
Ultra low jitter clock driving an asynchronous USB receiver
Runs on a single Li-ion power cell 2500mAh.
8-fold output buffer for a (near to) load independent output behaviour
4th order feedback loop for minimum distortion
Fixed, phase-shifted carrier wave oscillator decreases inter-channel distortion
Ultra low noise front end accepts any line level source without the need for impedance matching
