X5 PCM2706 + CS4344 + Two Parallel TDA1308 Output Board Amp USB DAC Finished Amp Bare Plate
Plate type: X5
Solution: PCM2706 + CS4344 + double TDA1308
Plate size: 65 * 68 mm (excluding terminal).
Because PCM2706 + CS4344 USB_DAC performance, on the basis of plus consists of two parallel TDA1308 output of headphones parts, suitable for 16-120 headset, actual audition performance is quite good.
Because the current is not large, with USB power supply directly, use more convenient, after tests on the layout of the wiring, signal-to-noise ratio reaches more than 90 db.
