The AD28MSP01KP-REEL from Analog Devices is a PSTN signal port IC in a 44-PLCC package, handling 16-bit resolution across two channels. Surface-mount 44-LCC (J-Lead) package with a 16.59x16.59 mm body — the J-bend leads save board space compared to a gull-wing, but the footprint is specific to PLCC sockets or direct solder.
Cross-reference to AD28MSP01KP
The AD28MSP01KP (without -REEL suffix) shares identical specs: 350 mW, 16-bit, 2-channel, surface-mount 44-PLCC. The only difference is packaging — the -REEL variant ships in bulk (tubes/trays) while the base AD28MSP01KP typically comes in tape-and-reel. Both are electrically identical, so a board designed for one accepts the other without layout changes.
