Housed in a 32-VQFN (4x4 mm) with an exposed thermal pad, the ADS1291IRSMR is a surface-mount part intended for reflow soldering. The small footprint suits two-layer medical PCBs where real estate is at a premium. The exposed pad must be soldered to a ground plane for thermal and electrical performance — standard practice for this package class.
The ADS1291IRSMR is listed as Active and ROHS3 compliant.
