REF3040AIDBZR

REF3040AIDBZR is the tape-and-reel SOT-23 ordering code for the Texas Instruments REF3040 voltage reference, listed as Active Production in the datasheet package option addendum with device marking R30E. Read on the REF3040 variant rows only - not on its REF30 siblings - it delivers 4.096 V held between 4.088 V and 4.104 V (0.2 % initial accuracy), a temperature drift of 35 ppm/°C typical and 75 ppm/°C maximum, a quiescent current of 42 µA typical and 50 µA maximum at 25 °C (59 µA maximum over the full -40 °C to +125 °C range), output noise of 45 µVpp in the 10 Hz to 1 kHz band, and an output current of 25 mA maximum, over -40 °C to +125 °C. The selection point is the 4.096 V level itself: it maps binary full-scale ranges onto round voltage steps for ADC and DAC reference pins, at a quiescent drain low enough for battery instruments. Selection advice: the REF30 family packs 2.5 V, 3.0 V, 3.3 V and this 4.096 V variant into the same SOT-23 footprint and similar markings - confirm the R30E marking on the offered reel, since a sibling code fits the footprint while shifting every conversion on the board. Parameters verified against the TI REF30 datasheet SBVS032 Rev. K (package option addendum and the REF3040 electrical rows).
