The E-DAC is a stand alone USB digital-to-analogue converter which comes in a small brushed aluminium enclosure smaller than a credit card where the output is provided by a 3.5mm line out jack.
The E-DAC has been designed by the prolific NwAvGuy and is based on the TE7022L UAC1 engine and ES9023 DAC chip. It supports 16 bit and 24 bit at sample rates of 44.1kHz, 48kHz and 96kHz. The on-board filtered power supply reduces noise levels to “practically non-existent levels” and a crystal controlled oscillator further improves performance levels. The end result is a ‘plug and play’ DAC which sports distortion of less than 0.005% and has a dynamic range of over 110dB.
