We make the parts that set creative people free™
General Description
The AL1201 stereo DAC is a high
performance 24-bit digital to analog audio
converter. Dynamic range is 107dB (A-
weighted). The sensible pinout and easy
user interface are unprecedented. The part
contains an internal high quality phase-
locked loop that eliminates the need for
external high frequency clocks.
