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. ## Lifecycle and sourcing The ADS1291IRSMR is listed as Active and ROHS3 compliant.","metaTitle":"TI ADS1291IRSMR 24-Bit AFE, 1-Ch, 495 µW, 32-VQFN","metaDescription":"Texas Instruments ADS1291IRSMR is a 1-channel 24-bit analog front-end IC for biopotential measurement. 495 µW power, 2.7-5.25 V analog supply.
