AL1101
24-Bit Analog-to-Digital Converter
General Description
The AL1101 is a 24-bit sigma-delta
stereo analog-to-digital audio converter
using Wavefront’s ClockEZ™ technology.
With dynamic range of 107dB, simplified
interface, and low power consumption,
the AL1101 (and its companion AL1201
DAC) is a best-in-class solution for
44.1kHz and 48kHz operation.
