The AD1895 is a 24-bit, high-performance, single-chip, second-generation asynchronous sample rate converter. Based upon Analog Devices experience with its first family of asynchronous sample rate converters (the AD1890 to AD1893), the AD1895 offers improved performance and additional features.
This improved performance includes a minimum THD+N of -115 dB for all input frequencies and sample rates, 128 dB dynamic range, 192 kHz sampling frequencies for both input and output sample rates, improved jitter rejection and 1:8 up-sampling and 7.75:1 down-sampling ratios. Additional features include a TDM mode to cascade multiple AD1895, more serial formats for better interfacing to digital signal processors and a bypass mode.
APPLICATIONS
- Home Theater
- Automotive Audio Systems
- DVD
- DVD-R
- CD-R
- Set-Top Boxes
- Digital Audio Effects Processors
Please see the AD1896, our highest end sample rate converter with even more performance and additional features like matched phase mode.
