General Description
The AL1101 stereo ADC is a high
performance 24-bit analog to digital audio
converter. Dynamic range is 107dB (A-
weighted). The sensible pinout and easy
user interface are unprecedented. The
part has an internal high quality phase-
locked loop that eliminates the need for
external high frequency clocks.

Note 1: passband, stopband, and highpass frequencies scale with Fs.
Note 2: passband is compensated for external single-pole 80kHz lowpass filter at
analog inputs (.26dB at 20kHz). Compensation scales with Fs.
