What the AD1895YRS is and where it fits
The AD1895YRS from Analog Devices is a stereo sample rate converter (SRC) for digital audio interfacing. It accepts an I²S serial audio input and resamples it to a different output rate, handling clock-domain crossing between asynchronous audio sources. The part operates from a 3.3 V to 5.5 V supply and covers -40°C to 105°C.
Package and mounting
Housed in a 28-SSOP (0.209", 5.30 mm width) surface-mount package, the AD1895YRS fits a standard fine-pitch SOIC footprint. The 28-SSOP body is narrow enough for dense layouts but still hand-solderable with a fine tip. No exposed pad — thermal dissipation is through the leads, so keep the copper pour under the package connected to the ground plane.
