Over the 165 °C span that gives a maximum shift of about 1.32 mV — equivalent to about 2 LSBs at 12 bits, or 0.5 LSB at 14 bits. For a precision ADC front end that budget is comfortable; for a 16-bit SAR converter you would want a lower-drift reference like the REF5025's sibling with 3 ppm/°C. ## Noise floor: 3 µVp-p — flicker-limited That is the 1/f flicker corner that dominates in weigh-scale, load-cell, and strain-gauge applications where the signal bandwidth is a few hertz. At 3 µVp-p the reference contributes less than 0.5 LSB of noise to a 14-bit measurement at 2.5 V full scale — clean enough for most industrial sensor interfaces. ## Active lifecycle — no obsolescence contingency No last-time-buy window, no forced migration to a successor part. ## Package and footprint — SOIC-8, standard land pattern The REF5025AIDG4 comes in an 8-SOIC package (0.154-inch body width, 3.90 mm). That is a common footprint shared by many precision references from TI, ADI, and Microchip — the part drops into existing layouts without a board spin.","metaTitle":"REF5025AIDG4 Voltage Reference, 2.5V ±0.1%, 8 ppm/°C","metaDescription":"Texas Instruments REF5025AIDG4 series voltage reference: 2.5V fixed output, ±0.1% tolerance, 8 ppm/°C drift, 3 µVp-p noise.
