The UD-01 USB DAC technology is based Burr-brown PCB2702E DAC chip architecture. It provides dual-channel storage for strong internal buffer. The Burr-Brown OPA2604 low-pass filters out output-stage preamp damages and residual digital garbage, and streams granted analogue sonic signals. The DC servo uses Texas low noise TL072 JEFT op amps to assign DC servo circuit and to prevent sonic impairment by coupling capacitors.
