REF5025AIDGKR

REF5025AIDGKR is the tape-and-reel VSSOP-8 ordering code for the Texas Instruments REF5025 2.5 V precision voltage reference, listed as Active Production in the datasheet package option addendum. The AI letters are the standard grade, and its figures are the ones on this page: initial accuracy of 0.1 % maximum, temperature drift of 8 ppm/°C maximum, output noise of 3 µVPP/V, long-term stability of 50 ppm over the first 1000 hours in the VSSOP package, input up to 18 V (the input must sit at least 0.2 V above the output), output current of ±10 mA and quiescent current of 0.8 mA typical, over −40 °C to +125 °C. The selection point is a low-noise, low-drift 2.5 V rail for 16-bit-class data acquisition at the standard grade’s cost point. Selection advice: grade discipline matters in this family — the high-grade I code (0.05 %, 3 ppm/°C) and the enhanced REF50E generation (0.025 %, 2.5 ppm/°C) carry tighter figures that do not transfer to the AI code, so if your error budget was drawn against those rows, order those codes instead. DGKR denotes the 8-pin VSSOP on a 2,500-piece reel. Parameters verified against the TI REF50 datasheet (package option addendum) and the TI product page.
