Fixed 2.5 V reference with sub-ppm noise floor
The REF5025IDGKR is a precision series voltage reference from Texas Instruments delivering a fixed 2.5 V output with ±0.05% initial accuracy.
Drift, drive, and supply headroom
Temperature coefficient is rated at 3 ppm/°C typ, so the output shifts less than 1 mV over a 125 °C span — critical for industrial sensor loops that see wide thermal swings. The 10 mA output current can serve multiple ADC reference inputs or a small resistive divider network without a buffer. Quiescent supply current is 1.2 mA, low enough for battery-powered instruments that cannot spare a separate LDO.
8-VSSOP package and temperature grade
Housed in an 8-VSSOP (3.00 mm × 3.00 mm body), the REF5025IDGKR fits compact analog front-end layouts where board area is tight.
