MANUFACTURER DATA REVIEW
Key technical specifications
Ordering-code highlights reviewed against official manufacturer documentation.
- Function
- 2.500 V series voltage reference · B grade (the grade letter in the model code), 8-lead SOIC
- Initial accuracy
- ±0.02% maximum (500 µV) for the B grade (Table 2, at VIN = 3 V to 15 V, IL = 0 mA, TA = 25 °C)
- Temperature coefficient
- 2 ppm/°C maximum (box method) over −40 °C to +125 °C for the B grade; 4 ppm/°C by the bowtie method (Table 2)
- Output noise
- 1.25 µV p-p typical, 0.1 Hz to 10 Hz; noise density 41.3 nV/√Hz at 1 kHz (Table 2). The 1 µV p-p figure in secondary copy is the 2.048 V ADR4520’s row
- Regulation
- Line regulation 10 ppm/V; load regulation 30 ppm/mA typical / 80 ppm/mA maximum sourcing and 60/120 ppm/mA sinking, IL = 0 mA to ±10 mA (Table 2)
- Supply and dropout
- Input range 3 V to 15 V; dropout 500 mV for this 2.5 V output part (the 300 mV family figure applies at VOUT ≥ 3 V); quiescent current 700 µA typical / 950 µA maximum, no load (Table 2)
- Absolute maximum ratings
- Supply voltage 16 V and storage −65 °C to +150 °C are Table 7 absolute-maximum figures, not operating ranges
- Order-code package
- R-8 package (8-lead SOIC), B grade, −40 °C to +125 °C (Ordering Guide, Table 14)
- Manufacturer packing
- Reel of 1,000 (Ordering Guide) · the guide prints no reel diameter — do not assume a 7-inch reel
