Product Summary

The al1201g stereo DAC is a high performance 24-bit digital to analog audio converter. Dynamic range is 107dB (Aweighted). The sensible pinout and easy user interface are unprecedented. The al1201g contains an internal high quality phaselocked loop that eliminates the need for external high frequency clocks.
