REF5025ID

REF5025ID is a Texas Instruments 2.5 V low-noise, very-low-drift precision voltage reference in 8-pin SOIC (D), tube packaging — ±0.05% maximum initial accuracy (high grade), 3 ppm/°C maximum temperature drift, ±10 mA source/sink output current that drives high-resolution ADC references without an external buffer, 3 µVPP/V output noise (7.5 µVPP at 2.5 V), 2.7 V to 18 V supply (VOUT + 0.2 V minimum), TRIM pin for ±15 mV adjustment, TEMP pin for temperature monitoring, −40 to +125 °C. The ±10 mA direct-drive output is the selection point: it replaces a buried-Zener reference plus a buffer op amp in one 8-pin part, with 3 ppm/°C drift that holds 16-bit-class accuracy across the industrial temperature range in process control, medical instrumentation and precision data acquisition. Selection advice: the I denotes the high grade (0.05% / 3 ppm); the standard grade REF5025AID is 0.1% / 8 ppm — pick by the system error budget, not by habit. The D is the SOIC-8 in tubes; the REF5025IDGKR is the VSSOP-8 tape-and-reel variant. TI lists REF5025ID as Active. Evidence: TI REF50xx datasheet (SBOS410) and distributor listings confirm 2.5 V, ±0.05%, 3 ppm/°C, ±10 mA, SOIC-8 and tube packing. Match the full REF5025ID code.
