AD1895AYRSZRL

Product Summary

The AD1895AYRSZRL is a 24-bit, high performance, single-chip, second generation asynchronous sample rate converter. Based upon Analog Devices’ experience with its first asynchronous sample rate converter, the AD1895AYRSZRL offers improved performance and additional features. This improved performance includes a THD + N range of –115 dB to –122 dB depending on sample rate and input frequency, 128 dB (A-Weighted) dynamic range, 192 kHz sampling frequencies for both input and output sample rates, improved jitter rejection, and 1:8 upsampling and 7.75:1 downsampling ratios. Additional features include more serial formats, a bypass mode, and better interfacing to digital signal processors. The applications of the AD1895AYRSZRL include Home Theater Systems, Automotive Audio Systems, DVD, DVD-R, CD-R, Set-Top Boxes, Digital Audio Effects Processors.
